U.S. Judge Larry Burns said he would consider enforcing the subpoenas if Wilkes’s lawyers could show that the lawmakers had specific information relevant to his defense, the Associated Press reported late Tuesday.

He is also considering subpoenas against up to 15 other House members and four senators, including: Larry Craig (R-Idaho), Daniel Inouye (D-Hawaii), Carl Levin (D-Mich.), and Jay Rockefeller (D-W.Va.).

Geragos also said he was trying to serve a subpoena on White House Chief of Staff Joshua Bolten.

Wilkes is accused of giving Cunningham more than $600,000 in cash as well as gifts and favors such as luxurious trips, antiques, boats and the services of prostitutes. In return, the California Republican allegedly helped secure $80 million in defense contracts for Wilkes’s firms. Cunningham is serving an eight-year sentence for accepting bribes from Wilkes and others.

Wilkes’s trial is scheduled to begin Wednesday when jury selection will take place; opening statements and first witnesses will not be heard until Oct. 9.

In another development in the Cunningham case, Judge Burns has postponed the trial of a defendant accused of conspiring to bribe the former lawmaker because the former has come down with meningitis.

John Michael, who is accused of money-laundering and obstruction of justice, was set to stand trial this week along with Wilkes.

Judge Burns did not set a new date for Michael. Wilkes and Michael have pleaded not guilty.

Besides Hastert, Hunter, Lewis, Doolittle and Issa, Wilkes’s legal team issued subpoenas for documents and testimony to eight other members of Congress in early September, including House Minority Whip Roy Blunt (R-Mo.), Pete Hoekstra (R-Mich.), Joe Knollenberg (R-Mich.), Jerry Weller (R-Ill.), John Murtha (D-Pa.), Silvestre Reyes (D-Texas) and Norm Dicks (D-Wash.). A 13th subpoena, issued to Rep. Ike Skelton (D-Mo.), was withdrawn earlier.
