“They’re trying to throw her in prison and throw her off the ballot,” Vance said in an interview with the Newsmax television channel.

“Look, that’s not democracy.”

He said Le Pen had been “leading in some polls” for France’s 2027 presidential election and had been convicted of an “incredibly minor charge that implicates, by the way, her staff, not even Marine Le Pen herself”.

Le Pen, considered a leading candidate in the 2027 election, was found guilty by a French court on Monday of embezzlement of European Parliament expenses and banned from running from public office for five years.

President Donald Trump compared Le Pen’s conviction earlier this week to his own legal battles.

“She was banned from running for five years and she was the leading candidate. That sounds like this country, that sounds very much like this country,” Trump said, describing the court ruling as “a very big deal”.

Trump was convicted in New York of falsifying business records to pay hush money to a porn star, but two federal criminal cases brought against him were dropped after he won November’s presidential election.
