There has been more that one congressman who has lost access to classified material. Leaky Leahy comes to mind.
He was a member of the senate intel committee, if not it’s chairman, when he blew an active intelligence source to the press.

“Losing access” isn’t the same as “losing clearance.”
Congressmen do not go through the formal clearance process e.g. SF85.
