The US House Intelligence Committee has called on President Donald Trump to produce evidence by Monday on his yet unfounded claim that his phones at Trump Tower in NY were wiretapped during last year's presidential campaign.
The comments came a day before Monday's deadline set by the House Intelligence Committee, asking the Department of Justice to provide any documentary evidence relating to Mr Trump's allegation, according to ABC News and the Associated Press.
Mr Spicer responded: "He doesn't really think that President Obama went up and tapped his phone personally".
The House Intelligence Committee also requested evidence by Monday in a letter sent to the Justice Department by the House committee chairman, Rep. Devin Nunes, R-Calif., and the panel's ranking Democrat, Rep. Adam Schiff, D-Calif., a senior congressional aide said Saturday.
But members of the House Intelligence Committee asked the Department of Justice to provide evidence of President Trump's claims by Monday.
Spicer also said that Trump's use of quotation marks in his tweet when referring to "wiretap" should be interpreted as "surveillance overall".
Also Monday, Spicer defended the Department of Justice's purging of Obama-appointed USA attorneys as "standard operating procedure" and said it doesn't matter that Trump had told high-profile Manhattan prosecutor Preet Bharara in November that he could stay on.
Tonight! Lacking evidence, White House advisor Kellyanne Conway struggles to back up Trump's wiretap claims. She added that one of these ways of monitoring includes "microwaves that turn into cameras", which we know as "a fact of modern life", she claimed.
Conway offered her own, clarification, saying, she was talking about overall spying and it was not a reference to Trump's wiretapping allegations.
"So far, I don't think the American people have gotten all the answers", Mr McCain said.
A spokesman for former President Barack Obama has denied the claims.
Other than Conway, the Trump Administration has stayed mum on its allegations that Obama was collecting data on their communications, likely because affirming the claims could reinforce the notion that the Trump campaign was communicating with the Russians.
Trump said in third message: 'How low has President Obama gone to tapp my phones during the very sacred election process.
