Live from NPR News in Washington, I'm Rylan Barton.

In recent weeks, President Trump has carried out a series of strikes on boats in the Caribbean, saying he's targeting Venezuelan drug cartels.

He also says the South American nation has, quote, emptied its prisons into the U.S.

Now he says he's expanding the campaign from sea to land.

As NPR's Tom Bowman explains, experts are questioning the legality of the attacks.

I have talked to a number of lawyers, former Jags, law professors.

They all have serious concerns about the legal rationale that's provided here.

They say that it's full of holes that it's essentially the president determining on his own by Dick Tot that we are in an armed conflict and that that gives

him the right to conduct these armed strikes in essence to kill people on boats in the Caribbean.

NPR's Ryan Lucas reporting. The Trump administration has struck a third drug company, struck a deal with a third

drunk company as part of its push to lower drug prices in America. This one focuses on drugs used in

vitro fertilization. NPR's Sydney Lupkin reports. President Trump announced drug maker EMD Serrano has

agreed to lower prices for its fertility drugs like Gano F sold directly to patients not using

their insurance. All told, the company's IVF drugs will be offered at an 84% discount. But the deal

doesn't include EMD Serrano's other drugs for things like cancer and multiple sclerosis.

The announcement is part of the president's push to bring U.S. drug prices in line with those paid in other countries, an effort he calls most favored nation pricing. And it follows his campaign promise to make IVF more affordable. A typical IVF cycle can cost as much as $30,000. And while drugs are part of that, they aren't the majority of the total cost. For its part, EMD Serrano will get an expedited FDA review of a new drug and relief from certain tariffs.
