Sen. Johnny Isakson (R-Ga.) is set to retire in approximately a month, creating an opening atop the Senate Ethics Committee, a behind-the-scenes panel responsible for enforcing standards of behavior for senators and their staffs and investigating potential violations of federal law or the Senate’s rules…

The lack of enthusiasm comes as the normally secretive committee has had high-profile investigations in recent years, putting a spotlight on why finding Isakson’s successor could prove difficult: No one relishes investigating their colleagues.

Sen. Roy Blunt (R-Mo.), another member of leadership, said he doesn’t know who will take over the committee. Asked if he was interested, he answered with an emphatic, drawn out “nooooo.”

Sen. John Cornyn (R-Texas), who previously served as vice chairman, acknowledged that it’s up to the leader but said he’s not interested.
