LANSING, Mich. (AP) — The Michigan House has voted to form a committee to investigate two embattled lawmakers who had an extramarital relationship.

In a resounding voice vote, the House late Wednesday backed the panel’s creation. House Speaker Kevin Cotter says he wanted to act in case an investigation turns up wrongdoing because the House isn’t back in session until after Labor Day.

He says the move keeps “all options open” and will let the committee meet earlier if he appoints members.

Republicans Reps. Todd Courser and Cindy Gamrat could be expelled from the Legislature.

The House Business Office may finish its inquiry next week. Courser has admitted orchestrating a fictional email that said he was caught having sex with a male prostitute to divert attention in case the affair got out.
