A Republican, who used to assist the previous president, was hospitalized due to a health condition.

Mike Pence underwent heart surgery at the Inova Fairfax Medical Campus in Falls Church, Virginia, after experiencing symptoms associated with a “slow heart rate.”

The former vice president had a routine operation, which involved installing a pacemaker to help control his heartbeat, on April 14.

The 61-year-old expressed gratitude towards the doctors, nurses, and other health professionals who work every day at the Inova Heart and Vascular Institute in Falls Church, 16 miles southwest of downtown Washington.

“I am grateful for the swift professionalism and care of the outstanding doctors, nurses, and staff at Inova Heart and Vascular Institute, including Dr. Brett Atwater and Dr. Behnam Tehrani,” Pence said in a statement obtained by Axios.

“I also appreciate the consultation of my longtime Indiana physicians, Dr. Michael Busk and Dr. Charles Taliercio at Ascension St. Vincent. My family has been truly blessed by the work of these dedicated healthcare professionals,” he added.

Pence’s representative expects the former vice president to make a full recovery and return to normality within days.

When former President Donald Trump nominated Pence for the vice president role in 2016, he disclosed medical records that showed he was diagnosed with an asymptomatic left bundle branch block.

Before leaving public office, Pence applauded President Trump for doing everything in his power to avoid creating new international military confrontations.

“I am proud to report with just a few days left in our administration, our administration is the first in decades that did not get America into a new war,” he said on Twitter.

In the past four years, the Trump administration championed peace by ordering U.S. armed forces to withdraw from war-torn Afghanistan, Iraq, and Somalia.

“That is peace through strength,” the former vice president said.

As earlier reported, Pence was criticized for writing a letter to House Speaker Nancy Pelosi in which he refused to invoke the 25th Amendment and overturn the November election.

“I do not believe that such a course of action is in the best interest of our nation or consistent with our Constitution,” he said at the time.

Pence claimed the 25th Amendment was intended to address presidential incapacity or disability and not as a means of punishment or usurpation. He stressed that invoking that amendment “would set a terrible precedent.”

He also said the previous Trump administration’s time and energy would be better “directed to ensuring an orderly transition” because it was a time for healing, not for divisiveness.

These remarks prompted Rep. Louie Gohmert (R-Tex.) and 11 other GOP members to sue the former vice president because refusing to invoke the 25th Amendment allegedly violated the U.S. Constitution, according to existing procedures for Congress to count electoral votes after a presidential election.

“This civil action seeks an expedited declaratory judgment finding that the elector dispute resolution provisions in section 15 of the Electoral Count Act … are unconstitutional because these provisions violate the elector’s clause and the Twelfth Amendment of the U.S. Constitution,” they said in a court document.
