Lindsey Graham's death increases urgency for Mitch McConnell's return to Senate
WASHINGTON – The sudden death over the weekend of Sen. Lindsey Graham is increasing the urgency in the Senate for Sen. Mitch McConnell to return to work to cushion the GOP's increasingly slim voting majority.
McConnell, 84, has been hospitalized for a month, and Graham unexpectedly passed away on Saturday, July 11 – leaving Senate Republicans down two key voting members.
South Carolina's governor is expected to quickly appoint Graham's interim replacement, who will serve until January. However, GOP lawmakers may not have enough support to advance key legislative priorities (or block certain Democratic bills) until then, especially with McConnell having no definitive return date.
Republican absences in the Senate have led to significant problems lately for President Donald Trump – most notably the passage of a largely symbolic rebuke of the war in Iran. Now that the conflict in the Middle East has ramped up again after Trump's peace deal deteriorated, similar votes could again be on the legislative horizon. It may not be easy for Republicans to succeed in blocking them.
The fragile dynamics underscore just how tight the margins are in Congress. As the midterm elections approach, every vote counts for Republican leaders in both the Senate and House of Representatives, and that political math will continue to individual members outsize power to influence the larger agenda on Capitol Hill.
Graham's office announced that he passed away due to a "brief and sudden illness." Emergency personnel said they were conducting CPR on a man suffering from cardiac arrest at an address listed as Graham's DC home, according to public safety radio feeds reviewed by USA TODAY. His cause of death still had not been publicly confirmed as of Sunday afternoon. He was 71.
McConnell was hospitalized on June 14. An initial, publicly available dispatch call indicated someone at the scene was unconscious. Another call, made several minutes later, showed someone was in cardiac arrest. McConnell's office neither confirmed nor denied the calls involved him.
Since then, his office has provided few details about what specifically happened, saying only that he's continued to improve and has spoken at length by phone in recent days with his Senate colleagues, including Senate Majority Leader John Thune. Thune said in mid-June he was "hopeful" McConnell would return within the week. That was roughly a month ago.
