After Tennessee Republican Sen. Bob Corker’s retirement announcement Tuesday, retired NFL quarterback Peyton Manning’s name quickly entered the conversation.

But Tennessee Republican Rep. Scott DesJarlais told Business Insider that Manning would likely choose to run for Sen. Lamar Alexander’s seat if he decides to retire in 2020.

Manning is close with Corker. The two were spotted exiting President Donald Trump’s motorcade in June at Trump National Golf Club in Virginia.

Manning also contributed to Corker’s Senate campaigns. During Corker’s first campaign in 2006, Manning gave Corker $2,100 in both the primary and general elections.

In Corker’s 2012 reelection cycle, Manning gave him $1,500 in the primary and $2,500 for the general election. In 2014, he also gave to Alexander’s re-election campaign.
