Former Vice President Mike Pence has made a decision on the presidential election between former President Donald Trump and President Joe Biden.

The former vice president said he will not endorse his former boss, former President Trump, but he will not vote for Biden.

“It should come as no surprise that I will not be endorsing Donald Trump this year,” the former vice president said to Fox News host Martha MacCallum.

“Look, I’m incredibly proud of the record of our administration,” the former vice president said. “It was a conservative record that made America more prosperous, more secure and saw conservatives appointed to our courts in a more peaceful world.”

“That being said, during my presidential campaign, I made it clear there were profound differences between me and President Trump on a range of issues, not just our difference on my constitutional duties that I exercised on Jan. 6,” he said.

The former vice president said it was the former president’s stance on the national debt, his new position on banning TikTok and his stance on abortion that contributed to his decision to not endorse his former boss.

“Last week [was] his reversal on getting tough on China, and supporting our administration’s effort to force a sale of ByteDance [and] TikTok,” the former vice president said.

But he was coy on who he would vote for.

“Like most Americans, I’m going to keep my vote to myself,” he said when asked who he would vote for.

“I would never vote for Joe Biden,” he said. “How I vote when that curtain closes, that will be for me.”

He also dismissed the idea of campaigning as a third-party candidate or endorsing a third-party candidate when he said, “I’m a Republican.”

The former vice president said he would not be campaigning against Trump but would campaign about “what we should be for.”

“Republican primary voters have made it clear, Martha, who they’re for in this election,” he said. I’m going to spend the rest of the year talking about what we should be for—the broad mainstream conservative agenda that has defined our party and always made America strong, prosperous, and free.”
