Last week, it was Bobby Knight.

And now, another former, prominent college coach has spoken up and endorsed Donald Trump as the next president of the United States.

Prior to the Indiana GOP primary on Tuesday, former Notre Dame coach Lou Holtz shared a message on Trump's Twitter account.

More from FoxSports

Greetings, I'm Lou Holtz, and I wholeheartedly endorse Donald Trump as the next president of the United States. There are nothing but winners in Indiana. The main reason I'm endorsing him is I've played his golf courses, I've stayed in his hotel, he does nothing but go first class in everything. He wants this country to be first class as well.

Thank you for listening.

It's worth noting that in 2008, Holtz reportedly donated to the campaign of Hillary Clinton.
