President Trump says he might accept dirt from another country on his potential Democratic rivals if offered, raising new questions and concerns about foreign influence on American elections.

"It's not an interference, they have information — I think I'd take it," Trump said. "If I thought there was something wrong, I'd go maybe to the FBI — if I thought there was something wrong."

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.

An incumbent president with a middling approval rating and mounting controversies is usually an easy draw for primary challengers.

Look to Gerald Ford, Jimmy Carter and George H.W. Bush. All three presidents survived intraparty battles, but those primary fights left their reelection campaigns so hobbled — exposing longstanding weaknesses with their bases — that each went on to lose out on four more years in the White House.

Donald Trump Jr. has reached a compromise with the Senate Intelligence Committee to testify before the panel, according to a source familiar with the negotiations. The deal comes less than a week after the committee's initial subpoena inflamed tensions between the GOP-led panel and the White House.

The mid-June interview will be limited in time — no more than four hours — although no topics are off limits, the source said.

Rep. Alexandria Ocasio-Cortez blasted "middle of the road" approaches on climate change, an apparent criticism of former Vice President Joe Biden.

Montana Gov. Steve Bullock announced on Tuesday that he's running for president, appealing to primary voters as a Democrat elected twice in a largely Republican state and joining a primary field of nearly two dozen candidates.

Bullock is focusing his campaign message on campaign finance, touting Montana's election laws that he has championed as attorney general and governor, and promising to "take our democracy back."

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.

He met with the committee in December 2017 about his participation in a June 2016 meeting at Trump Tower with Russians offering "dirt" on Hillary Clinton.

After months of oscillating speculation, followed by a long ramp up that drew out uncomfortable reassessments of his long public career, former Vice President Joe Biden has announced that he will run for president in 2020.

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.

Vermont Sen. Bernie Sanders released 10 years' worth of tax returns Monday. The documents underscore how much money the populist presidential candidate has earned in recent years, as his public profile has risen.

In an interview with the New York Times before the returns were made public, Sanders dismissed the idea that his newfound wealth undercut his billionaire-bashing message.

Democrats in Congress and an overwhelming majority of the American public are eagerly awaiting the expected release this week of the Mueller report.

President Trump confirmed reports that he is strongly considering sending detained immigrants in the country illegally to "sanctuary cities" to try to punish Democrats who have opposed his stringent immigration proposals. The comments came hours after White House and Homeland Security officials said the idea had been scrapped.

"We'll bring them to sanctuary city areas and let that particular area take care of it, whether it's a state or whatever it might be," Trump told reporters at the White House on Friday.

The Treasury Department and the Internal Revenue Service did not meet House Democrats' deadline to turn over President Trump's past tax returns by Wednesday, escalating what will likely culminate in a legal battle in the investigation into the president's personal and business finances.

Ohio Rep. Tim Ryan is the latest Democrat to join the growing field seeking the 2020 presidential nomination.

Ryan announced his intentions on ABC's The View on Thursday, telling the panel that he is running to be a champion for manufacturing in a country that has been fractured by trade and outsourcing.

"I understand that legacy of job loss. ... I understand where we need to go. The country's so divided right now that we can't get a plan together. The first thing we ought to do is unify," Ryan said.

A former Nevada Democratic assemblywoman and candidate for lieutenant governor has come forward detailing an unwanted encounter with Vice President Joe Biden when he campaigned for her in 2014.

Attorney General William Barr has told congressional leaders that he anticipates being able to give them a redacted version of special counsel Robert Mueller's report on his investigation into Russia's interference with the 2016 presidential election by "by mid-April, if not sooner." Democratic lawmakers have been pushing for lawmakers to see the full report without redactions, though members of both parties have called for its public release.

After nearly two years of waiting, special counsel Robert Mueller's report into Russia's attack on the 2016 presidential election is finally done. And there's growing bipartisan pressure on Attorney General William Barr to make it public.

The world of political fundraising is about to get a lot more complicated and confusing thanks to a federal court ruling that could lead to the rise of more groups that seek to raise money off of a candidate's name, even if the group has nothing to do with that candidate.

On Thursday, U.S. District Judge Tanya Chutkan struck down the Federal Election Commission's rules that prohibited unauthorized political committees from using a candidate's name.
