A federal appeals court on Friday upheld the convictions of three top staffers on Ron Paul's 2012 presidential campaign who were found guilty of arranging for money to be funneled through a vendor to an influential Iowa state senator who dropped his support for another Republican candidate in favor of Paul.

Campaign chairman Jesse Benton, campaign manager John Tate and deputy campaign manager Dimitri Kesari were convicted in 2016 of causing false records to be filed, causing false campaign expenditure reports, engaging in a false statements scheme and conspiring to commit the offenses. Kesari was sentenced to three months in prison while the other two got probation. They have completed their sentences but are seeking to clear the felony convictions from their records.

The three argued that they broke no laws when they paid a video production company, which passed on $73,000 to then-Iowa state Sen. Kent Sorenson, who withdrew his support from Michele Bachmann and backed Paul six days before the 2012 Iowa caucuses. Sorenson also was convicted in the scheme and sentenced to 15 months in prison. He was released in April.
