Senator John McCain has said US President Donald Trump should provide proof that former president, Barack Obama, wiretapped his phones or he should retract the claim.
The White House also says it expects the Justice Department to comply with a request to provide lawmakers with evidence on President Donald Trump's accusation that his predecessor wiretapped his NY skyscraper.
The White House has yet to provide any evidence to back President Trump's claim that President Obama tapped his phone during the campaign.
President Trump again ignored questions about what evidence he has to back up a week-old claim on twitter that President Obama tapped his phones at Trump Tower.

Spicer was then asked if President Trump intends to be taken seriously at all times and if he wants his claims to be taking literally.
The House Intelligence Committee's Republican chairman Devin Nunes and top ranking Democrat Adam Schiff have written to the Justice Department asking for evidence to be provided in support of the allegation.
Both Mr Obama, through a spokesman, and his director of national intelligence James Clapper, have denied ordering any wiretapping operation targeted at Mr Trump.
"And I answered about surveilling generally", Conway said.
The House intelligence committee said it would give the department until March 20 to comply with the evidence request.
"If you look at the president's tweet, he said wiretapping in quotes".
"I have no evidence, but that's why there's an investigation in Congress", Conway told anchor George Stephanopoulos.
"All I said to the Bergen Record is - I was making a comment about the articles from this past week where it is revealed that one can be surveiled in any number of techniques", Conway said.
The U.S. Justice Department is requesting more time to respond to a congressional inquiry into President Donald Trump's unproven assertion that he was wiretapped by his predecessor.
