"If, however, Director Brennan's statement is purely political and based on conjecture, the president has full authority to revoke his security clearance as head of the Executive Branch", Burr's statement continued.
"Few Americans have done more to protect this country than John", McRaven said.
The decision to strip Brennan of his clearance on Wednesday represents an unprecedented presidential intervention.
John Brennan wrote that it is "critically important" that special counsel Robert Mueller be permitted to complete his investigation into Russian interference in the 2016 election and whether Trump's campaign coordinated with Russia.
High-ranking government officials sometimes retain security clearances after leaving office to advise their successors as needed, and some private sector companies can also require them.
"Security clearances for those who still have them may be revoked, and those who have already lost their security clearance may not be able to have it reinstated".
"Through your actions, you have embarrassed us in the eyes of our children, humiliated us on the world stage and, worst of all, divided us as a nation", he continued.
"I don't trust many of those people on that list", he said.
'Queen of Soul' Aretha Franklin has died at 76
By the time she was 14, Aretha had already given birth to two children: Clarence Franklin , 63, and Edward Franklin , 61. Over the course of her career she won 18 Grammy Awards , including the Lifetime Achievement Award in 1994.
In response to the White House's move, Brennan tweeted that he "will not relent".
"So I think it's something that had to be done", he added.
Trump on Wednesday announced that he was revoking Brennan's security clearance as a result of national security concerns, though the move was widely viewed as an effort by the president to silence one of his most fervent critics.
In a statement, Senate Intelligence Committee chairman Richard Burr, R-N.C., cited a New York Times op-ed published Thursday, after Brennan's security was revoked, in which Brennan wrote that Trump's claims of no collusion were "hogwash", saying the only remaining questions were whether the collusion amounted to a criminal conspiracy and whether the Trump team obstructed justice in order to cover up the collusion Brennan alleged.
Trump has ordered a review for nine others who have clearances.
Sanders says the security clearances of other current and formers officials are also "under review".
He has previously described as "treasonous" the joint press conference Mr Trump held with Russian leader Vladimir Putin in Finland last month. U.S. Representative Joaquin Castro said Mueller should also investigate the issue now that Trump has tied it to the Russian Federation probe. "I think they're not good people".
