Massachusetts Sen. Elizabeth Warren controlled the debate early with a progressive policy pitch. She and New York City Mayor Bill de Blasio said they would eliminate private insurance in favor of "Medicare-for-all." Former Housing and Urban Development Secretary Julián Castro was aggressive on immigration, backing decriminalizing illegal border crossings.

President Trump officially launched his 2020 reelection bid on Tuesday at a massive rally in Orlando, though much of the event picked up where his 2016 campaign left off.

Trump relished in reliving his unlikely victory 2 1/2 years ago over Democratic nominee Hillary Clinton. As the crowd broke into chants of "lock her up," he teased about still trying to search for missing emails on her private server and the possibility his Justice Department could look into prosecuting the former secretary of state.

President Trump will officially kick off his 2020 reelection campaign with a rally in Florida on Tuesday night. But in reality, he has been running for a second term ever since he took office.

The mayor of America's biggest city, New York's Bill de Blasio, is jumping into a presidential race where an expansive Democratic field includes the man running a city about 99% smaller.

The Senate intelligence committee has issued a subpoena to Donald Trump Jr., the president's eldest son, to testify again before the panel, according to a source familiar with the subpoena.

Massachusetts Rep. Seth Moulton is joining the large 2020 Democratic presidential field, touting a record of military service, bucking his party and arguing for younger leadership.

"The greatest generation saved our country from tyranny. It's time for our generation to step up and do the same," Moulton said in an announcement video posted early Monday.

Attorney General William Barr said there would be no obstruction of justice charges against the president stemming from the report by special counsel Robert Mueller, which was released in redacted form on Thursday.

But the threshold for charging the president might have been breached, had staffers not resisted his directives to engage in actions that would have impeded the investigation.

Special counsel Robert Mueller did not find evidence that President Trump's campaign conspired with Russia to influence the 2016 election, according to a summary of findings submitted to Congress by Attorney General William Barr.

"The Special Counsel's investigation did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russia in its efforts to influence the 2016 U.S. presidential election," Barr wrote in a letter to leaders of the House and Senate judiciary committees on Sunday afternoon.

Former Colorado Gov. John Hickenlooper has announced he will seek the Democratic nomination for president in 2020, becoming the second governor to join a crowded field of candidates.

The testimony on Wednesday from Michael Cohen, President Trump's former personal lawyer who is headed to federal prison in early May, was a potentially seminal moment in the myriad investigations into the Trump administration House Democrats are expected to launch now that they control the chamber.

Sen. Bernie Sanders of Vermont is giving it another go, launching a second campaign for the White House four years after surprising Democrats with a strong bid for the party's 2016 nomination.

"We began the political revolution in the 2016 campaign, and now it's time to move that revolution forward," the independent senator told Vermont Public Radio in an interview airing Tuesday morning.

Calling it "a great thing to do," President Trump declared a national emergency on Friday in order to help finance a long-promised wall on the U.S.-Mexico border. It's a highly unusual move from an unconventional president.

A federal judge has ruled that President Trump's former 2016 campaign chairman Paul Manafort intentionally lied to special counsel Robert Mueller's office after agreeing to cooperate with its investigation into interference by Russia into the last presidential election.

The ruling from Judge Amy Berman Jackson means prosecutors are no longer bound by their plea deal with Manafort, who now faces the prospect of spending the rest of his life in prison.

President Trump used his second State of the Union address to call for bipartisanship and unity, even as he remains at an impasse with Congress over immigration in the shadow of the longest government shutdown in U.S. history.

Sen. Cory Booker of New Jersey is the latest Democrat to enter the increasingly crowded race for the White House, making the initial announcement with a message of unity.

With the government reopened — at least for now — following a 35-day partial government shutdown, President Trump's State of the Union address has been rescheduled for Tuesday, Feb. 5.

In a letter sent to the president on Monday, House Speaker Nancy Pelosi, D-Calif., wrote that the two had agreed upon the new date next week, after she had postponed her original offer of Jan. 29 amid the shutdown.

Updated at 9:45 p.m. ET

The longest government shutdown in history ended after President Trump signed a bipartisan three-week stopgap funding measure late Friday. Several agencies had been partially shuttered for 35 days.

"I am very proud to announce today that we have reached a deal to end the shutdown and reopen the federal government," Trump said earlier Friday in the White House Rose Garden, announcing the long-awaited bipartisan breakthrough.

California Sen. Kamala Harris is running for president in 2020. The first-term Democratic senator made the announcement on ABC's Good Morning America Monday morning.

"I love my country, and this is a moment in time that I feel a sense of responsibility to fight for the best of who we are," Harris said.

New York Sen. Kirsten Gillibrand says she is running for president, joining a growing number of Democrats who are seeking to challenge President Trump in 2020.

Gillbrand announced her decision on CBS's The Late Show with Stephen Colbert, saying she is filing her exploratory committee for the White House on Tuesday evening.

President Trump made his case to the American people Tuesday night for why a massive wall along the Mexican border is necessary, using his first Oval Office address to outline his conditions for ending the 18-day-and-counting partial government shutdown.

Updated at 10:15 p.m. ET

The White House is planning a media blitz as President Trump pushes for a wall along the Southern border, which congressional Democrats have repeatedly rebuffed. This week's events involving the president come as a partial shutdown of the federal government drags into its third week with no apparent end in sight to the impasse.

Republican and Democratic lawmakers alike, along with military leaders, are reacting with sadness and concern over Defense Secretary Jim Mattis' sudden resignation announcement.

A retired Marine Corps four-star general, Mattis is widely seen as one of the most respected members of President Trump's Cabinet and was confirmed by the Senate on the same day as Trump's inauguration in a near-unanimous vote.

Adult film star Stormy Daniels, who says she had a sexual encounter with Donald Trump more than a decade ago, has been ordered to pay him nearly $293,000 for attorneys' fees and another $1,000 in sanctions after her defamation suit was dismissed.

President Trump claimed some personal victories in the 2018 midterm results, and as he ticked them off at a news conference on Wednesday he might as well have been walking through the Electoral College map for 2020.

There are dozens of competitive races across the country that will determine control of the House, Senate and governors' seats. Democrats need to pick up 23 seats to take back the House, Democrats need a net gain of two seats to flip the Senate and Democrats are expected to slice into Republicans' 33-16 advantage in governors' seats.

President Trump began his rally in Wisconsin Wednesday night by condemning apparent explosive devices sent to former President Barack Obama, former Secretary of State Hillary Clinton and others, saying that "any acts or threats of political violence are an attack on democracy itself."

"No nation can succeed that tolerates violence or the threat of violence as a method of political intimidation," Trump said, pledging an "aggressive investigation" that will bring the suspects to justice "hopefully very soon."
