WASHINGTON (AP) — House investigators say they have issued subpoenas to House Republican Leader Kevin McCarthy and four other GOP lawmakers as part of their probe into the Jan. 6 insurrection. It’s an extraordinary step that has little precedent and is certain to further inflame partisan tensions. The Jan. 6 panel’s subpoenas for McCarthy of California and Republican Reps. Jim Jordan of Ohio, Scott Perry of Pennsylvania, Andy Biggs of Arizona and Mo Brooks of Alabama come as the investigation is winding down and as the panel prepares for a series of public hearings this summer.
