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."

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.

A day after U.S. and Mexico officials announced an agreement to avert tariffs — set to begin on Monday — affecting billions of dollars in imports from Mexico, President Trump took a victory lap on Twitter.

Under a joint agreement released by State Department officials, Mexico will assist the United States in curbing migration across the border by deploying its national guard troops through the country, especially its southern border.

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.
