Former vice president Joe Biden is trying to fix his repeated gaffes on the campaign trail, but he only seems to be making matters worse.

Biden recently told a gun control forum in Des Moines, Iowa that he met with survivors of the mass shooting in Parkland, Florida “when I was vice president,” despite the fact that the shooting took place a year after he left office.

On Tuesday, Biden was back in Iowa to fix the mess, though he admits the details of the visit are fuzzy.

“I also met with the kids from Parkland, in the Capitol,” Biden said at a campaign stop. “I was no long … I was still called vice president, but it was in 18.

“And I watched them. They asked me to come up and speak to them in the rotunda. I think it was the rotunda, one of the buildings, one of the rooms in the Capitol,” Biden said. “And they were all about to go and try to lobby congressmen and senators in the halls of the Congress and Senate.

“And they … were trembling in their boots, they didn’t want to meet these kids,” he said. “Not a joke. Not a joke.”

Video shows Biden’s private meeting with Parkland students was not in the Capitol rotunda as he recalled. It wasn’t even in the Capitol building.

NBC News interviewed Biden just before he ducked in to the March 23, 2018 meeting in room “SD-G32” – located in the basement of the Dirksen Senate Office Building across the street from the Capitol.

Biden’s bumbling excuse for his previous misstatements is only the latest in a series of blunders that have become a joke of the 2020 Democrat presidential primary, with even Biden referring to himself as a “gaffe machine,” CNN reports.

Nearly every week, Biden says something not woke, or racist, or just plain wrong.

The flub wasn’t even the only one on Tuesday.

Discussing the volatile politics of Biden’s younger years, he alleged Bobby Kennedy and Dr. Martin Luther King Jr. were assassinated in the “late 70s,” missing the mark by a decade, according to Fox News.

“Just like in my generation, when I got out of school, when Bobby Kennedy and Dr. King had been assassinated in the ‘70s, the late ‘70s when I got engaged,” he said.

Kennedy and King were murdered in 1968, and Biden married his first wife, Neilia, Hunter, in 1966, according to the Washington Examiner.

Two weeks ago, Biden told an Asian & Latino Coalition PAC in Iowa that “poor kids are just as bright and just as talented as white kids,” only to correct himself moments later by adding “wealthy kids, black kids, Asian kids.”

It was the same week he also told the Iowa State Fair that Democrats “choose truth over facts.”

Those comments followed others that have forced the 76-year-old career politician to change his policy positions, correct the record, or apologize for putting his foot in his mouth.

He’s touted his excellent working relationship with segregationists, performed a flip-flop-flip on support for the Hyde Amendment ban on taxpayer funded abortions, repeatedly confused British Prime Ministers Margaret Thatcher and Teresa May, alleged “eight more years of Trump” will change America, and created words that don’t exist like “expodentially.”

The missteps, however, are nothing new for Biden, who witnessed both of his previous presidential campaigns go down in flames in Iowa following similar problems over the last four decades.

“It was in Iowa in 1987 when Biden sealed his own fate in the first of his three presidential runs by lifting phrases from a speech by British opposition leader Neil Kinnock without attribution,” the Examiner reports. “Weeks later, he dropped out amid mounting claims of plagiarism and exaggeration.

“His second presidential run was in 2008, when he dropped out after receiving .9% of the vote in the Iowa caucuses, finishing fifth behind Barack Obama, John Edwards, Hillary Clinton, and Bill Richardson.”
