Top Trump advisor Kellyanne Conway also defended the business mogul's unsourced allegations and insinuated that he may have additional information.
Democrats, meanwhile, are demanding that the DoJ name a special prosecutor to investigate alleged ties between Trump campaign aides and Russian Federation.
So, where did this all start?
Last October, The New York Times reported that the FBI pursued a broad inquiry into Trump's links to Russian Federation and Putin, but the investigation failed to yield any incriminating evidence.
He's president of the U.S.! The article states that a June warrant request was denied, and that a second request in October was approved.
"As part of that practice, neither President Obama nor any White House official ever ordered surveillance on any US citizen". When she claimed that Trump's assertions about Obama wiretapping him had been widely reported, Stephanopoulos interjected, "That is simply not true ..." Levin said March 5.
On Sunday, Mr Trump demanded that they broaden the scope of their inquiries to include Mr Obama's potential abuse of executive powers.
What do intelligence officials say about the allegations?The Justice Department and FBI haven't commented, although a senior USA official confirmed to NBC News that FBI Director James Comey asked the agency to publicly knock down Trump's claim. The Justice Department hasn't said anything.

Those people, who continue to remain in the sieged Mosul, are on the verge of a humanitarian disaster. For its part, the United Nations said it is working as fast as possible to help those displaced.
Categorically, none. When he made the allegation, without consulting any aides or security agencies, uninhibited by the traditional protocols of his office, on the basis alone of the claim of a notorious "fake news" site, Trump - no longer candidate, but President Trump - made the most serious charge of criminality against Barack Obama. He also said he "can deny" that a FISA order existed to monitor Trump Tower.
What is the FISA court again?
The DoJ must obtain a warrant from the secretive Foreign Intelligence Surveillance Court before placing a communications wiretap.
As NPR's Justice Correspondent Carrie Johnson says: "No". "The wiretapping has been discussed in The New York Times, BBC, Fox News, and we believe that it should be looked at by the House Intelligence Committee".
Because the requests and the FISA court orders are secret, it's hard to get information about them.
The president sparked a firestorm on Saturday by leveling a stunning and unsubstantiated accusation against his predecessor , suggesting Obama ordered surveillance on his residence at New York's Trump Tower. "He is the president of the United States", she told Fox News on Monday. "He could also easily ask the appropriate agencies whether there was a wire tap".
We know Russian ambassador Sergei Kislyak's phone is routinely tapped, and that calls he made to Mike Flynn, since resigned as national security adviser, were intercepted by the Federal Bureau of Investigation on its own initiative. "The question is who they did spy on and the extent of the spying that is the Trump campaign, the Trump transition, Trump surrogates". If they're going to investigate Russian Federation ties, let's include this as part of it.
