McCain’s office confirmed the fundraiser to The Hill while reiterating that the Arizona senator has not made a final decision about running again. His office said he will be prepared regardless. 

Buzzfeed first reported the fundraiser, which will be held Jan. 28, for “his first DC re-elect reception.”

McCain has said he is strongly considering a run for reelection in 2016, after he joked last year this term could be his last in the Senate.

The former GOP presidential nominee also hosted a fundraiser in New York last month. In that invitation he asked donors to join him while “I consider running for reelection to the U.S. Senate.”

The 27-year veteran of the Senate won his last election in 2010 with 60 percent of the vote, and had a little more than $1.1 million in cash on hand in the third quarter last year. 

During a New York Times profile published in December, McCain expressed concern about how retiring might affect his health. He is 77 years old. 

“My grandfather actually flew home from the peace-signing on the Missouri and died,” McCain said. “I have seen people age dramatically when they go into retirement.”
