U-S President Donald Trump has made a very bold accusation.
He said his predecessor tapped his phones during last year's election.
Trump announced the allegations against former president Barack Obama in a series of tweets, saying he just found out that "Obama had my wires tapped in Trump Tower.''
Trump didn't offer any evidence and didn't allude to what prompted the allegation.
He has a residence in Trump Tower and largely ran his transition out of the New York City highrise.
There was no response yet from Obama.
