Sen. Jim Inhofe, R-Okla., is home in Oklahoma this week recovering from quadruple bypass surgery.

Inhofe, 78, went in for the surgery on Friday. "During a routine doctor's visit last week, my doctor found that I had serious problems with my heart which resulted in quadruple bypass surgery this past Friday in Tulsa," Inhofe said in a statement. "The discovery shocked me as I had no visible symptoms that something was wrong.

"Today, I am feeling great and am fully engaged with my work here in Oklahoma," he added.

It's unclear when Inhofe will return to Washington, DC, but he urged his colleagues to pass legislation to end the government shutdown.

"I encourage my colleagues in Washington to work with vigilance to reopen the government with a bill that represents Oklahomans and all of Americans," Inhofe said "I may miss some upcoming votes on the Continuing Resolution, but my doctors agree I will return soon and even stronger to continue the fight to protect Oklahomans' freedoms."
