House Rules Chairman David Dreier (R-Calif.) abruptly adjourned a hearing on a GOP health care repeal bill Thursday after he became aware that Rep. Pete Sessions was not sworn in as a Member of the 112th Congress, committee spokeswoman Jo Maney said.

The Texas Republican was not on the floor during Wednesday’s swearing-in ceremony, and neither was incoming freshman Mike Fitzpatrick (R-Pa.). Under the Constitution, which was read on the House floor Thursday, only sworn Members of Congress are allowed to conduct official business, but Sessions and Fitzpatrick have already voted eight times in the 112th Congress.

While it was previously thought that Sessions had introduced the motion to create the rules for the Rules Committee, Maney said it was later determined that Rep. Virginia Foxx (R-N.C.) was the Member who offered the package.

Dreier is consulting with the parliamentarian about how to best craft a unanimous consent agreement to rectify the situation, Maney said.
