The brother of Democrat vice presidential nominee Tim Walz is considering endorsing former President Donald Trump and hinted that he could release dirt on his sibling in the run-up to the November election.

Jeff Walz made the remarks about his brother in social media posts that were unearthed last week by the New York Post.

The story comes as Tim Walz is facing increased scrutiny after being caught making misleading claims about IVF, his DUI arrest, past accomplishments, and misconstruing his military service.

When someone on Facebook suggested that he talk to his brother, who is the governor of Minnesota, Jeff Walz said that they had not spoken in eight years.

“I’m 100% opposed to all his ideology,” Jeff Walz said.

He also indicated that he was never informed in advance that his brother was going to be Vice President Kamala Harris’ pick for VP.

“My family wasn’t given any notice that he was selected and [was] denied security the days after,” he said.

Another person on Facebook suggested that he “get on stage with President Trump and endorse him” at a political rally.

“I’ve thought long and hard about doing something like that! I’m torn between that and just keeping my family out of it,” Jeff Walz said. “The stories I could tell. Not the type of character you want making decisions about your future.”

Jeff Walz told the Post that he was currently not doing any interviews.
