A pair of Republican lawmakers are pushing back on news of the House Ethics Committee extending investigations into them, though it’s unclear if the two cases are related.

The bipartisan lower chamber committee, which reviews alleged misconduct among members and is referred matters from the Office of Congressional Ethics, separately announced the investigations on Thursday into Reps. Ronny Jackson (R-TX) and Wesley Hunt (R-TX). The announcements provided no details about the allegations, which for both members reportedly pertain to payments the Republicans made from their campaign committees at private clubs.
