Former President Donald Trump took aim at Sen. Jon Tester (D-Mont.) over the weekend, telling supporters he looks pregnant, among other insults about the senators weight.

Trump made the offensive remarks at a private event at his Mar-a-Lago club and residence in South Florida during a fundraiser for Rep. Ronnie Jackson (R-Texas), who was Trumps White House physician.

Hes now in a tough campaign, and he could very well lose. We ought to go up and campaign against him, Trump said about Tester, according to a recording of the remarks obtained by The Washington Post and Politico . In fact, I looked at him, and I said, Oh, this finally works for a man or woman, because he looks pregnant to me.

Have you seen this guy? He doesnt look like a fat guy, except his stomach is out to here, Trump said to laughter. Not that I talk about things like that. I dont even notice them.
