Earlier this month, Jill Biden, wife of presumptive Democratic presidential nominee Joe Biden, began taking a more public role in her husband’s bid for the White House, participating in media interviews and campaign events.

However, Joe Biden has not been out and about as much as the former second lady, which has raised questions about the former vice president and his campaign.

During an interview with Mobile radio’s FM Talk 106.5’s “The Jeff Poor Show,” U.S. Rep. Gary Palmer (R-Hoover) asked that question and offered a theory as to why that is the case.

“Here’s Jill Biden, living in the same house with Joe Biden, who is out doing interviews, who is out in meetings,” Palmer said. “She’s in her 60s. She’s not as old as Joe but I believe she is in her 60s, in that age group that is considered at risk. She is able to go out and meet with people. She is able to do interviews face to face but Joe can’t. So people ought to be asking themselves a question: Why is it he can send his wife out but he can’t go out?”

“There are a number of people who have a theory on that, not the least of which is he is a gaffe machine,” he added.

Palmer reminded listeners how Joe Biden’s struggles with gaffes go back decades.

“My first contact with Joe Biden was the very first work that I did in D.C. when I ran the think tank,” Palmer added. “That was Clarence Thomas’ confirmation hearing. And you may recall he had gone through controversy then … It is well known that he is surrounded in controversy and that he is a gaffe machine.”
