WASHINGTON (AP) — The Latest on President Donald Trump (all times local):

4:15 p.m.

White House Press Secretary Sean Spicer is suggesting the Trump administration may crack down on states that have legalized recreational marijuana.

Spicer says during a press briefing Thursday that the issue rests with the Justice Department. But he says, "I do believe that you'll see greater enforcement of it."

He adds that it's "something that the Department of Justice I think will be further looking into."

President Donald Trump said as a candidate that he supports medical marijuana. But Spicer says there's a big difference between that and the recreational use of the drug.

The Justice Department has several options available, including filing lawsuits on the grounds that state laws regulating pot are unconstitutional because they are pre-empted by federal law.

President Donald Trump says he will bring the "full force and weight" of the U.S. government to combat an "epidemic" of human trafficking.

The president is meeting at the White House with senior advisers and representatives of organizations that deal with trafficking. His daughter, Ivanka Trump, is among those in attendance.

Trump calls human trafficking a problem that is "not talked about enough." He says he will order the departments of Justice and Homeland Security to take a hard look at the resources they are devoting to addressing the issue.
