U.S. President Donald Trump is asking Congress to probe "potentially politically motivated investigations" during the 2016 campaign, the White House said Sunday.
An Obama spokesman has denied Trump's accusation as "simply false."
In his statement, White House Press Secretary Sean Spicer referred to unspecified reports of "potentially politically motivated investigations immediately ahead of the 2016 election" as "very troubling."
"President Donald J. Trump is requesting that as part of their investigation into Russian activity, the congressional intelligence committees exercise their oversight authority to determine whether executive branch investigative powers were abused in 2016," Spicer said.
He added that there would be no more comment on the matter from Trump or the White House.
Trump leveled his charges against Obama early Saturday, at the end of a week in which his administration was battered by controversy over communications between Russian officials and some of his senior aides including Attorney General Jeff Sessions.
