U.S. Sen. Shelley Moore Capito has joined the list of Republicans who have called for President Joe Biden to resign from office following his announcement that he would no longer seek reelection.

“We live in a dangerous world and deserve a commander in chief who is up for the rigors of the job,” Capito, R-W.Va., said in a statement released late Monday morning. “If President Biden feels that he is not capable of making it through the demands of a campaign, then how could he be capable of serving out the rest of his term as president?”

Capito’s voice joins a GOP chorus in calling for Biden’s resignation. House Speaker Mike Johnson, R-La., also has made that demand, as has Sen. Rick Scott, R-Fla., and Sen. Steve Daines, R-Mont., the National Republican Senatorial Committee Chair.

Capito also focused comments on Vice President Kamala Harris, who Biden endorsed for the Democratic nomination for president. Harris said she would “earn and win” the nomination at the Democratic National Convention in Chicago.

“Make no mistake, Vice President Kamala Harris represents a continuation of the last four years of President Biden’s disastrous policies,” Capito said. “Whether it’s her failed leadership on our out-of-control southern border or her deciding vote in passing the so-called Inflation Reduction Act that supercharged the skyrocketing inflation Americans still feel to this day, a Harris administration would be more of the same. As the vice president who cast more tie-breaking deciding votes than any vice president in history, she alone put our nation on the path of misguided progressive policies and nominations outside of the mainstream.

“What is even worse is that members of President Biden’s inner circle–including Vice President Harris, White House officials, and Democrat leadership–have let him continue on amidst his apparent cognitive decline. The Biden administration consistently fails to accept responsibility for its many failures. They owe the American people an explanation, most recently in their inadequate and irresponsible actions following the assassination attempt of President Donald Trump.”
