It's the standard repug modus operandi.
Today:At issue is whether Congress can compel the president to allow top aides to answer questions under oath. The House Judiciary panel issued subpoenas for White House Chief of Staff Joshua Bolten and former White House counsel Harriet Miers to answer questions about last year's US attorney firings.
Responding to a similar probe on the Senate side,
the president has offered to allow Mr. Rove and other officials to answer questions not under oath and without an official transcript. Responding to the new subpoenas on Thursday, deputy White House press secretary Tony Fratto urged Congress to accept the president's accommodation. "Every day this Congress gets a little more out of control," he said.

Cox subsequently issued a subpoena to President Nixon, asking for copies of taped conversations recorded in the Oval Office and authorized by Nixon as evidence.
The president initially refused to comply with the subpoena, but on October 19, 1973, he offered what was later known as the Stennis Compromise—asking U.S. Senator John C. Stennis to review and summarize the tapes for the special prosecutor's office.
