Telegraph - Donald Trump has said he "very seldom" regrets anything he posts on Twitter, when asked about the volley of tweets he sent two weeks ago accusing Barack Obama of spying on him.
The president brushed off questions about his claims without evidence that his predecessor wiretapped him during last year's presidential campaign.
Mr Trump, speaking at a press conference with German Chancellor Angela Merkel, said "at least we have something in common," apparently referring to reports during Obama's presidency that the United States bugged her phone.
Congressional leaders from both political parties say they do not believe Trump was wiretapped.
Mr Trump also deflected criticism about a White House official who on Thursday repeated a charge that a British intelligence agency helped Obama wiretap Trump. Trump said Press Secretary Sean Spicer was merely quoting a Fox News analyst when he made the comments.
