President Trump says his request for Ukraine to investigate former Vice President Joe Biden was driven by his concerns about corruption.

"This is not about politics, this is about corruption," Trump said last week. "If you look and you read our Constitution and many other things, I have an obligation to look at corruption."

But anti-corruption advocates say his administration's record of fighting corruption is weak and not in line with Trump's rhetoric.

President Trump held a press conference Wednesday with visiting Finnish President Sauli Niinistö, as the impeachment probe into Trump's conduct intensifies.

Trump faced questions about the House inquiry that was sparked by a whistleblower complaint that accuses Trump of pressuring Ukraine's president to investigate former Vice President Joe Biden and his son Hunter.

It's no secret that former national security adviser John Bolton did not see eye to eye with President Trump on a whole range of subjects.

But in his first public remarks since his ouster earlier this month, Bolton made clear just how deeply disconnected he was from his former boss on how to handle North Korea.

The whistleblower complaint released Thursday charges that White House officials attempted to limit access to potentially damaging details about President Trump's call with Ukraine's president by using a classified system reserved for highly sensitive information.

At the U.N. General Assembly in New York on Tuesday, President Trump told world leaders to reject "globalism" and to look out for the interests of their own countries first.

"The future does not belong to globalists; it belongs to patriots," Trump said.

Tuesday marked Trump's third address to the General Assembly as president. As he has done in the past, Trump used his remarks to the international organization to make the case for his "America first" style of diplomacy that puts nationalism ahead of multilateral efforts.

A House committee will take up legislation on Tuesday aimed at preventing mass shootings, as lawmakers and the White House move to respond to a recent spate of attacks across the country.

The bills being considered by the House Judiciary Committee include measures that would limit access to high-capacity gun magazines and block any person convicted of a hate crime from obtaining a firearm.

Former Vice President Joe Biden and Sen. Cory Booker went head-to-head over their records on criminal justice on the second night of the Democratic presidential primary debate in Detroit.

This was a fight that had been brewing for a while. The New Jersey senator spent the past few weeks repeatedly criticizing Biden for his role, when he was a Delaware senator, in crafting the landmark 1994 crime law that many criminal justice reform activists identify as one of the major contributors to the swelling of the U.S. prison population.

Labor Secretary Alexander Acosta is stepping down after criticism over his role in a nonprosecution deal reached years ago with the well-connected businessman accused of sex crimes, Jeffrey Epstein.

Acosta appeared on Friday at the White House with President Trump and announced his resignation.

"I do not think it is fair for this administration's Labor Department to have Epstein as its focus rather than the incredible economy we have today," Acosta said. "The right thing was to step aside."

President Trump is standing by Labor Secretary Alexander Acosta, at least for now.

Acosta is facing calls for his resignation after new sex trafficking charges were filed against multimillionaire Jeffrey Epstein on Monday.

Tucked into the 2017 law intended to cut Americans' taxes was a program aimed at helping communities struggling with high unemployment and run-down housing.

What's not clear is who's actually getting the most assistance from it.

The program allows investors to defer and potentially lower their capital gains taxes in exchange for investing in designated low-income neighborhoods.

Sen. Kamala Harris of California directly challenged former Vice President Joe Biden over his past opposition to federal busing policy, in a heated exchange on the second night of the first Democratic presidential primary debate.

This issue, from early in Biden's lengthy career in Congress, has hung over his campaign for president, creating a clear target for challengers to his front-runner status.

President Trump is threatening to use "overwhelming force" against Iran, after Tehran lashed out at the U.S. over the latest round of sanctions against the regime.

"Any attack by Iran on anything American will be met with great and overwhelming force. In some areas, overwhelming will mean obliteration," Trump tweeted.

Later at a White House event, Trump said he's prepared for whatever happens next with Iran.

President Trump attended a sumo wrestling competition with Japan's prime minister, Shinzo Abe, on Sunday, as the Japanese rolled out the red carpet for Trump during his visit to Tokyo.

The wrestler who won the competition received a U.S.-made trophy named the President's Cup, in honor of Trump's trip.

"That was something to see these great athletes, because they really are athletes," Trump said after the tournament. "It's a very ancient sport and I've always wanted to see sumo wrestling, so it was really great."

Should people convicted of a crime be allowed to vote while in prison?

It's a question that's divided 2020 Democratic presidential candidates and sparked attacks from President Trump and his allies.

At a CNN town hall event on April 22, presidential hopeful and Vermont Sen. Bernie Sanders was asked whether his support for allowing inmates to vote would extend to Boston Marathon bomber, Dzhokhar Tsarnaev. Tsarnaev has been sentenced to death for his role in the 2013 attack.

President Trump will meet with South Korean President Moon Jae-in at the White House on Thursday, as Moon attempts to get U.S. talks with North Korea back on track.

It will be the first meeting for Moon and Trump since the failed summit in Hanoi, which ended with no agreement from Trump and North Korea's Kim Jong Un on denuclearization.

President Trump is backing down from his threat to shut down the U.S. Southern border as soon as this week.

Trump had issued the warning in a bid to curtail surging border crossings by asylum-seekers from Central America. Instead, he is now giving Mexico "a one-year warning" to address his concerns about its handling of immigrants traveling through the country on the way to the United States. He also demanded that Mexico tamp down on the flow of drugs.

After spending 15 years in prison for a drug offense, Randy Rader had almost lost hope that he might get out of prison before his release date in 2023.

If Rader's conviction for 5 grams of crack cocaine — his third drug offense — had happened after 2010, he would have received a much shorter sentence. But the 2010 Fair Sentencing Act, which cut down on the disparity between penalties for crack cocaine and powder cocaine, did not apply to those already serving time.
