美众议院委员会要求川普提出监听指控的证据

The U.S. House Intelligence Committee is calling on President Donald Trump to produce evidence by Monday on his so-far unfounded claim that his phones at Trump Tower in New York were wiretapped during last year's presidential campaign.

Last week, the president wrote on Twitter that former President Barack Obama, a Democrat, had the phones at Trump headquarters tapped, but the Republican Trump has offered no evidence. The president tweeted, "Terrible. Just found out that Obama had me 'wires tapped' in Trump Tower just before the victory. Nothing found. This is McCarthyism."

Committee chairman Devin Nunes, a Republican, and Adam Schiff, the committee's ranking Democrat, sent a letter to Trump requesting the evidence to support his wiretap claim.

An Obama spokesman has said Trump's charges are "simply false." Trump has not commented on the wiretaps since the tweets.
