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.
