President Donald Trump has no regrets about tweeting that Barack Obama wiretapped him, the White House says.
The president has provided no firm evidence to back up his claim in the face of numerous denial yet refuses to withdraw it.
He's also hasn't put in a call to his FBI chief to ask him directly, his spokesman on Tuesday admitted.
'I think if we were start to get involved you would then write stories about how we're getting involved. So it's a no- win situation,' White House Press Secretary Sean Spicer said.
President Donald Trump has no regrets about tweeting that Barack Obama wiretapped him, the White House says
For the fourth day since Trump's tweet, the White House on Tuesday was unable to offer evidence to substantiate the president's claim that the previous Oval Office occupant gave his administration permission to listen to his adversary's calls.
Spicer repeatedly invoked a congressional committee that's reviewing the matter, which he said is the 'appropriate' entity to pursue an investigation.
As he did Monday, Spicer pointed to a Sunday statement ending White House commentary until the House Intelligence Committee probe is completed.
'Nothing has changed...it's not a question of new proof or less proof or whatever. The answer is the same,' Trump's spokesman said.
The White House official said he had not asked the president about his rational for attacking the previous administration in the way that he did but was confident that he doesn't regret it.
'No. Absolutely not,' Spicer said.
He likewise told a reporter asking if the president would take the claim back, 'Why would he withdraw it until its...adjudicated?'
The White House had initially provided a list of news reports it said backed up the president's claim. It backed away from that explanation after fact-checkers pointed out that none of the pieces alleged that Obama was wiretapping him.
On Tuesday Spicer argued that the president's tweet should be take at face value. He wants congressional committees to look into the wiretap charges because 'they have the appropriate venue and capabilities to review this.'
'It's not a question of prove it....it's that they have the resources and the clearances and the staff to fully and thoroughly and comprehensively investigate this,' he said.
Trump hasn't put in a call to his FBI chief to ask him directly. FBI head James Comey is seen today in Boston
'I think if we were start to get involved you would then write stories about how we're getting involved. So it's a no- win situation,' White House Press Secretary Sean Spicer said of Trump's refusal to call Comey and ask him if he was wiretapped
A spokesman for Obama and the former director of national security, James Clapper, have denied that Trump was wiretapped.
So did Comey, according to senior officials who spoke anonymously.
A tap would be illegal unless it's court ordered. Comey is said to have asked the Justice Department to smack Trump's claim down in order to protect the bureau from charges of illegal conduct.
The White House said Monday that it didn't believe reports claiming to represent Comey's position. The president's counselor, Kellyanne Conway, urged the FBI director to come forward and address to allegations in his own words.
Asked today if Trump had talked to Comey about his belief that he was wiretapped, Spicer said, 'No the president has not.'
White House officials have said it may be inappropriate for Trump and Comey to have that discussion and directed further inquires to the White House's Office of Legal Counsel.
