Will the NSA Whistleblower Get to Testify?

The Moonie Republican newspaper has a very interesting article published today. It seems there was a former NSA employee reading the NY Times about the illegal eavesdropping. He immediately wrote the House and Senate Intelligence Committees that he has evidence of "unconstitutional" activities ordered by the White House.
Will the Republican Congress allow Bush to be investigated? Or will Bush be able to continue his witch hunt seeking the lead source for the NY Times article.
The Washington Times

A former National Security Agency official wants to tell Congress about electronic intelligence programs that he asserts were carried out illegally by the NSA and the Defense Intelligence Agency.


Russ Tice, a whistleblower who was dismissed from the NSA last year, stated in letters to the House and Senate intelligence committees that he is prepared to testify about highly classified Special Access Programs, or SAPs, that were improperly carried out by both the NSA and the DIA.


"I intend to report to Congress probable unlawful and unconstitutional acts conducted while I was an intelligence officer with the National Security Agency and with the Defense Intelligence Agency," Mr. Tice stated in the Dec. 16 letters, copies of which were obtained by The Washington Times.


The letters were sent the same day that the New York Times revealed that the NSA was engaged in a clandestine eavesdropping program that bypassed the secret Foreign Intelligence Surveillance Act (FISA) court. The FISA court issues orders for targeted electronic and other surveillance by the government.
