What happens if Trump tries to ban a commercial?

The Department of Homeland Security has asked Congress to pass a new law that would prohibit the president from restricting a commercial activity unless it’s in the national interest.

The move comes as Trump faces growing criticism over the Trump International Hotel and Tower in downtown Washington.

The president has accused Democratic senators of wanting to block the hotel and has suggested the hotel is a violation of federal law.

The hotel is owned by a foreign government.
