Vice President Joe Biden will announce Tuesday that the Obama administration has "completed or made significant progress" on 21 of 23 executive actions to try to reduce gun violence developed after the mass shooting in Newtown, Conn.

They include ending the freeze on gun violence research, addressing barriers that keep states from submitting records to the national background check system and making sure federal law enforcement agencies trace guns recovered in investigations.

Biden will give his first extensive remarks on gun control since the Democratic-controlled Senate rejected a slew of gun control proposals – expanding background checks, renewing an assault weapons ban and limiting the size of ammunition clips – in April. He will use his 1 p.m. event at the White House comlex to again urge Congress to act.

"The administration has work to do…but Congress must also do its job," a senior administration said in a preview of Biden's remarks.

The official declined to say who Obama or Biden has met with on Capitol Hill to try to change votes, but said that Republican and Democratic senators who voted against the popular bill to expand background checks have faced an intense backlash.

"The politics of the issue are starting to change," the offical said.

Following the school shooting in December left 20 children dead, Obama pressed Congress to pass the nation’s most aggressive gun control plan in generations. He also proposed 23 executive actions that required no congressional approval.

Also on Tuesday, the left-leaning Center for American Progress will call on Congress to remove language from the annual appropriations bill that prevents the Bureau of Alcohol, Tobacco, Firearms and Explosives from requiring dealers to conduct a once-a-year audit on their inventories for missing guns. Obama removed the language from his proposed fiscal year 2014 budget proposal to Congress.

Below is a list of executive actions:

Obama later this evening will deliver remarks at a White House Lesbian, Gay, Bisexual Transgender Pride Month celebration in the White House's East Room.

President Obama has a full day of fundraising today at events in Boston and Miami. He leaves the White House this morning for Boston where he'll deliver remarks at a fundraiser for Senate candidate, Rep. Ed Markey and the Massachusetts Democratic Party.

Democrats are pushing hard to retain the seat vacated by Obama's appointment of Sen. John Kerry as Secretary of State, and Vice President Joe Biden delivered remarks at a Markey fundraiser Tuesday night, telling the crowd it's important for the party to keep the seat in Democratic hands as he accused the Republican party of cowing to conservatives Sen. Rand Paul and Ted Cruz.

"It's a pretty simple proposition: The United States of America, and the state of Massachusetts, does not need another Republican in the Senate," Biden said. "I'm being straight about this. This is not your father's Republican Party. It really is a fundamentally different party. There's never been as much distance, at least since I've been alive, distance between where the mainstream of the Republican congressional party is and the Democratic Party is. It's a chasm. It's a gigantic chasm."

Obama will leave Boston for Miami where he'll deliver remarks at two Democratic National Committee fundraisers.

Sen. Frank Lautenberg, a New Jersey Democrat who died Monday at age 89, will lie in repose in the U.S. Senate chamber Thursday afternoon.

Lautenberg's casket is due to arrive at the Capitol. A color guard ceremony is scheduled on the East Front steps, starting at 1:30 p.m.

The casket will then be taken inside the Capitol, where Lautenberg will lie in repose on the Lincoln catafalque in the Senate chamber during the afternoon.

Lautenberg was the Senate's oldest member and the last of its World War II veterans. He was eulogized Wednesday at a New York City synagogue. He was remembered as champion of transportation and environmental causes. Vice President Joe Biden, who served with Lautenberg in the Senate, was among the speakers.

Is Hillary Clinton fading already?

A new Quinnipiac national poll found her favorability numbersm while still ove 50 percent, have dropped. "Her score is down ubstantially from her all-time high score in February," said assistant poll director Peter Brown. "The drop in her favorability is substantial among men, Republicans and independent voters."

One reason for the drop, he said, "may be that 48 percent of voters blame her either a little or a lot for the death of the American ambassador in Benghazi,” Brown added.

Clinton still does well. The former Secretary of State leads Republican Sen. Rand Paul of Kentucky 49 – 41 percent and former Florida Gov. Jeb Bush 48 – 40 percent in trial matchups for the 2016 presidential race.

And she's still ahead of Vice President Joseph Biden, who trails Bush 44 – 38 percent and Paul 43 – 39 percent.

President Obama and First Lady Michelle Obama will host Dilma Rousseff, the president of Brazil, for an official state visit and a state dinner at the White House on Oct. 23.

The announcement of the special event comes as vice president Joe Biden is in Brazil, at the close of a three-nation tour of the region. Rousseff last visited Washington in April 2012, following Obama's visit to Brazil in March 2011.

The White House says the visit will allow the two presidents to continue "developing and strengthening the strategic partnership" between the two countries. It said the two will highlight the importance of expanding dialogue and cooperation on a number of bilateral, regional and global issues, "as well as the deep cultural ties and friendship that exist between the people of our two countries."

Biden, in Rio on Wednesday said Rousseff's visit would be "the only state visit that will occur in Washington this year." 

Vice President Joe Biden opened a Jewish American Heritage Month celebration with a poke at his boss -- and himself -- as he asked for a teleprompter to be removed.

"You can't tell Barack that the teleprompter's down," Biden said. "The standing joke in the office is Barack's learning to speak without a teleprompter; I'm learning to speak with one."

Biden is widely considered to be pondering a third presidential run and the speech was at least the third he's made in the past month to a key Democratic constituency. In his remarks, he credited Judaism with inspiring the U.S.

"The core, core, core basic values that make us distinguished from almost every nation is the heritage that you're celebrating in Jewish Heritage Month," he said. "The truth is that Jewish heritage, Jewish culture, Jewish values are such an essential part of who we are that's it's fair to say that Jewish heritage is American heritage."

His remarks at the reception at the American Institute of Architects building on New York Avenue were delayed as he called Oklahoma Thunder forward Kevin Durant for giving $1 million for tornado relief.

Introduced by Rep. Debbie Wasserman Schultz, who sponsored the heritage legislation, Biden credited her work during the 2012 campaign, saying she was "one of the reasons why Barack and I were reelected."

With immigration reform up for debate in the Senate, President Obama and vice president Joe Biden met Tuesday with a group of young immigrants who received deferred action and with siblings and spouses of undocumented immigrants.

The White House called the meeting an "important opportunity" for Obama and Biden to meet with "families who are directly affected by our nation's broken immigration system." It said the two were "moved" by what they heard and that the "Dreamers shared how their lives have been positively affected by the deferred action process and emphasized that they and their families need a permanent solution that will allow them to fully contribute to the country they call home."

The White House says Obama -- who has been buffeted in recent weeks by a trio of controversies -- "reiterated his commitment to passing a bipartisan, commonsense immigration reform bill this year." It said that although a Senate bill under consideration, "is not perfect, it does represent an important step towards the broad principles that need to be part of any immigration reform package."

The White House said Obama "encouraged them to continue to share their stories with the American public to move the hearts and minds of individual leaders and to propel the immigration debate forward."

The White House today released the President and Vice President's 2012 financial disclosure reports -- as required by the Ethics in Government Act of 1978.

The act requires high-level federal officials to publicly disclose their personal financial interests and the WHite House says its "serves to prevent financial conflicts of interest by providing for a systematic review of the finances of government officials." 

The White House says neither Obama nor Biden had "any conflicts of interest, and their reports have been reviewed and certified by the independent Office of Government Ethics."

The forms show Obama is still receiving royalties from his books, two between $100,000 and $1 million and one between $50,000 and $100,000. Biden's books don't appear to be as best selling: he reported royalties of less than $201 for his books.

Vice President Joe Biden will travel to Brazil, Colombia and Trinidad and Tobago during the last week of May.

In each country, Biden will meet with  leaders to discuss a range of bilateral and regional issues, including the economy and security.

"This trip will be an important chance to discuss our collective efforts to promote economic growth and development, access to energy and our ongoing collaboration on citizen security," according to the White House.
