Lindsey Graham may have some explaining to do upon his next golf outing with former President Donald Trump, if there is one.

At the very least, some awkward moments may occur when the duo get-together.

The South Carolina GOP senator supposedly had some profane and positive things to say about POTUS 45 in a new book called “The Divider: Trump in the White House, 2017-2021.”

It is authored by Peter Baker, the chief White House correspondent for the New York Times, and New Yorker magazine columnist Susan Glasser, both of whom presumably check all the liberal boxes; the title of the book may convey all you need to know about where they are coming from.

According to Axios, which apparently obtained a review copy, Graham “called his friend Donald Trump “‘a lying mother—-er’  but ‘a lot of fun to hang out with.’ Graham said it with ‘a what-can-you-do shrug,’ the authors report — the mindset of so many Trump allies and enablers.”
