The White House has called for the US Congress to investigate President Donald Trump's claim Barack Obama ordered Trump Tower to be "wiretapped" during the US election.
In a series of tweets, White House press secretary Sean Spicer called Mr Trump's allegation, for which he has provided no evidence, "very troubling".
He said Mr Trump is requesting Congress examine whether "executive investigative powers were abused" during the 2016 election campaign, as part of an ongoing congressional probe into Russia's influence on the election.
