Trump eggs on scrutiny of former NSA Rice's role in 'unmasking' campaign aides

United States President Donald Trump has urged the scrutiny of former president Barack Obama's national security advisor Susan E. Rice's alleged role in 'unmasking' campaign aides, who were swept up in intelligence monitoring.

Trump retweeted a story by a portal called 'The Daily Caller' under the headline 'Rice ordered spy docs on Trump?'

The story, which cites former U.S. Attorney Joseph diGenova as its source, claims Rice asked U.S. spy agencies to produce 'detailed spreadsheets' of phone calls involving Trump and his aides during the campaign.

The Obama administration's national security advisor played a central role in 'unmasking' several Trump campaign officials who had been swept up in U.S. surveillance operations against foreign targets during last year's presidential election campaign, according to current White House officials and sources on Capitol Hill.

Rice had requested that names be provided for otherwise unidentified U.S. people in dozens of raw intelligence reports relating to the Trump campaign, sources told The Washington Times on Monday.
