In the 2016 election cycle, Treasury Secretary Steven Mnuchin donated to only one Democratic Senate candidate.

But it wasn’t Sen. Joe Manchin III of West Virginia, the only Democrat who voted to confirm him for the position Monday night and who is up for re-election next year. It was freshman Sen. Kamala Harris of California, who has her own history with the new Cabinet official and voted against Mnuchin’s nomination.

Mnuchin gave Harris’ campaign $2,000 last year, according to records from the Federal Election Commission, making her the only Democrat who ran on the national level to receive money from him that cycle.

Tyrone Gayle, Harris’ press secretary, questioned the idea that a campaign contribution would influence her vote.

“Sen. Harris thoroughly evaluates each nominee based on their record and confirmation hearing — nothing else,” Gayle said in an email. “Sen. Harris believes Secretary Mnuchin’s record of profiting off of the misfortune of thousands of families who lost their homes during the U.S. mortgage meltdown made him unqualified to manage our nation’s finances and advocate for working people.”
