Former Vice President Mike Pence is among a crowd of candidates who are vying for the Republican Party's presidential nomination.

While Pence has sought to distance himself from former President Donald Trump, one bombshell moment from his time in the Trump White House keeps coming up. 

Voter says Pence should have stopped 2020 election from being certified

According to Fox News, the former vice president was confronted this week by a woman in Sioux City, Iowa who argued that he could have stopped the 2020 election from being certified.

"If it wasn't for your vote, we would not have Joe Biden in the White House," the woman told Pence at a campaign event on Wednesday.

"Joe Biden shouldn't be there, and all those wonderful things that you and Trump were doing together would be continuing, and this country would be on the right path," the voter insisted.

"Do you ever second guess yourself? That was a constitutional right that you had to send those votes back to the states," she added.

Pence: "No vice president in American history" stopped an election's certification

The woman's complaints echo those that former President Trump has been putting forward for the past two and a half years.

States want to correct their votes, which they now know were based on irregularities and fraud, plus corrupt process never received legislative approval. All Mike Pence has to do is send them back to the States, AND WE WIN. Do it Mike, this is a time for extreme courage!

While Pence remained polite he was nevertheless firm in his response, saying, "I'm sorry ma'am, but that's actually what the Constitution says."

"No vice president in American history ever asserted the authority that you have been convinced that I had," he continued.

Poll shows Trump far ahead of Pence

"But I want to tell you, with all due respect, I said before – I said when I announced, President Trump was wrong about my authority that day, and he's still wrong," the former vice president concluded.

Pence has struggled to gain traction in the GOP primary race, with most polls showing Trump to be the clear frontrunner.

A survey carried out by Echelon Insights between June 26 and June 29 put Pence's support at 5% among voters compared with 49% who back Trump.
