The Republican chairman of the US House of Representatives intelligence committee, Devin Nunes, said members of Trump's transition team were caught up in incidental surveillance targeting foreigners.
Donald Trump's communications may have been picked up in intelligence gathering on suspected foreign agents, according to allegations made on Wednesday by the Republican head of the House intelligence committee.
Devin Nunes, who worked on Trump's transition team and is now leading an investigation into possible links between that campaign team and Russia, said Trump's communications may have been intercepted late last year.
Nunes, however, said there was no evidence that then-president Barack Obama ordered the surveillance – as Trump has claimed – or that the Republican billionaire was the target.
Rather, Nunes suggested, Trump's communications were picked up during court-approved targeting of suspected foreign intelligence operatives.
The communications were not linked to Russia, he said, adding that they appeared to have "little or no intelligence value."
"The president himself and others in the Trump transition team were clearly put into intelligence reports," Nunes told reporters in front of the White House after briefing the president on the situation.
The information collected – spanning the November-January period between Trump's election victory and his inauguration – was "widely disseminated" in US intelligence circles, he said.
US intelligence community rules dictate that information on Americans picked up incidentally in surveillance must be scrubbed or masked in intelligence reports.
Nunes suggested those involved in the surveillance had violated those rules.
As for Trump, he indicated he felt vindicated by the revelation.
"I somewhat do. I must tell you I somewhat do," he said during a separate White House meeting.
"I very much appreciated the fact that they found what they found."
Terrible! Just found out that Obama had my "wires tapped" in Trump Tower just before the victory. Nothing found. This is McCarthyism!— Donald J. Trump (@realDonaldTrump) March 4, 2017
On March 4, Trump implied his predecessor had broken the law in targeting him.
"Terrible! Just found out that Obama had my 'wires tapped' in Trump Tower just before the victory. Nothing found. This is McCarthyism!" he tweeted.
The claim has snowballed into a political scandal that has called Trump's credibility into question and damaged relations with foreign intelligence partners.
Inquiry in jeopardy?
Nunes' revelation also threatened to upend a bipartisan investigation into alleged Russian interference in the November election and Moscow's possible collusion with the Trump campaign.
Adam Schiff, the ranking Democrat on Nunes' committee, voiced anger that the Republican had taken the information to the president – and the media – before the committee had been consulted.
The chairman, he said, "shared this information with the White House before providing it to the committee, another profound irregularity," he said.
