Donaldson also pointed to Bloomberg's ability to self-finance his campaign, which will let him "compete aggressively against Trump's massive political machine."

Like Trump, Bloomberg is a billionaire, though he has a larger net worth than the president, roughly $60 billion.

"He will make sure our government regains the trust of the American people, restores our standing in the world, and helps all Americans lead better and happier lives," Donaldson added.

Despite skipping the first four Democratic nominating contests, Bloomberg is picking up steam in the national polls.
