As chair of the Senate Judiciary Committee, U.S. Sen. Dick Durbin (D-Illinois) wants GOP megadonor Harlan Crow to give the committee information about the lavish trips, gifts, $100,000 tuition and property he gave Supreme Court Justice Clarence Thomas.

“The letter that the Committee received last night from a law firm representing Harlan Crow did not provide a credible justification for the failure of Mr. Crow and three corporate entities to respond to the Committee’s written questions,” Durbin said in a statement.

“Harlan Crow believes the secrecy of his lavish gifts to Justice Thomas is more important than the reputation of the highest court of law in this land. He is wrong,” the statement said.

Durbin is promising reforms in the wake of a Pro Publica expose on Thomas’ conduct. “As I’ve said many times before: The Chief Justice has the power to establish a credible, enforceable code of conduct for the Court today. However, if the Court will not act, this Committee will.”

The Senate Judiciary Committee asked Chief Justice John Roberts to appear at a hearing in April to discuss ethics reforms for the high court. He declined.

Durbin joined “Chicago Tonight” to talk about ethics reforms at the high court, the growing migrant crisis and the possibility that the federal government could default on the national debt.
