President Donald Trump believes Michael Flynn should "testify and do what he has to do to get story out," White House press secretary Sean Spicer said in his daily press briefing.

Earlier Friday, NBC News reported, citing congressional sources, that the Senate Intelligence Committee rejected the embattled former national security advisor's request for immunity from prosecution in exchange for his testimony into Russia's alleged meddling in the 2016 election.

Flynn's lawyer said in a statement that no "reasonable person" would get questioned in "such a highly politicized, witch hunt environment without assurance against unfair prosecution."

When a reporter asked if Flynn should testify under immunity, Spicer said he was not in the business of giving legal advice. The White House spokesman said that matter is up to Flynn and his lawyer. He said, the White House isn't worried that Flynn has damaging information on the president.

On Friday morning, Trump argued that Flynn "should ask for immunity" in the ongoing probe into possible ties between the Trump campaign and Russia. The president argued that concerns over Russia were a "witch hunt" of "historic proportion" by media outlets and Democrats.

@realDonaldTrump: Mike Flynn should ask for immunity in that this is a witch hunt (excuse for big election loss), by media & Dems, of historic proportion!
