The Senate vote was triggered by Sen. Josh Hawley and Rep. Scott Perry, who both submitted a protest of the electors from the commonwealth. While the House went to a debate over the objection, Senate Republicans agreed not to debate the objection before taking a vote.
Sen John Kennedy (R-LA), supported the objection to Arizona did not support the objection to the electoral voters from Pennsylvania.
The Senate remains adjourned until the House finishes debate over the Pennsylvania electoral college vote for President-elect Joe Biden over President Donald Trump.
