He’s got a seemingly unlimited supply of campaign cash and Michael Bloomberg is throwing it around — the multibillionaire just hired away one of his Democratic rivals’ top staffers.

Bloomberg hired Kelly Mehlenbacher, who had worked in operations for California Sen. Kamala Harris’ 2020 presidential campaign. She will be joining Team Bloomberg as its deputy chief operating officer, a Bloomberg spokesperson confirmed Thursday.

Mehlenbacher’s move comes following recent staff shakeups — including layoffs — at Harris’ sagging campaign as the only black woman in the race shifts her immediate focus to trying to win Iowa.

The political operative was among a group of staffers who recently quit Harris’ team following the latest series of layoffs there, according to Politico, which first reported the Bloomberg hire.

Mehlenbacher’s long resume also includes working as the treasury manager for Hillary Clinton’s failed 2016 presidential bid.

Reps for Harris’ campaign and Mehlenbacher did not immediately respond to requests for comment.

Although Bloomberg’s campaign wouldn’t address how much the ex-New York City mayor, who is worth an estimated $54 billion, will be paying Mehlenbacher, the deep-pocketed media mogul is already sparing no expense when it comes to his campaign.

Bloomberg is throwing another $9.5 million into television ads in major markets like Los Angeles and Houston less than a week after purchasing $30 million in spots to launch his 2020 bid.

The 30-second spots, scheduled to run Dec. 4 to Dec. 9, are shorter than the minute-long ads Bloomberg took out to announce his candidacy.

Bloomberg’s self-funded campaign already includes a long list of familiar folks.

Kevin Sheekey, a top adviser for Bloomberg at Bloomberg LP and when he was mayor, is his campaign manager.

Bradley Tusk, Bloomberg’s campaign manager in his third bid for mayor, is serving as an outside adviser, and Bill Knapp is doing Bloomberg’s ads, the same role he played during his mayoral races.
