WASHINGTON - President Donald Trump said Tuesday that he thinks it's "good" that Michael Bloomberg may run for president in 2020 and predicted that the billionaire former mayor of New York, who was formerly a Republican and independent, would not make it through the Democratic primary.

"I think the Democrats will eat him up," Trump said in an interview with Fox Business network's Trish Regan. "You know, you have a lot of people running. I'm hearing names that are shockingly bad, but they're nasty."

Bloomberg announced last week that he has registered as a Democrat. He has said that he will "take a look" at a potential White House bid after the midterms. In the meantime, he has committed to spending up to $100 million this year in support of Democratic House and Senate candidates, including a $20 million donation to the main Democratic Senate super PAC this month.

Trump told Regan that he is "100 percent" planning to run for re-election in 2020. He also dismissed the chances of Michael Avenatti, the lawyer representing adult-film actress Stormy Daniels.

"Oh, I don't think he's a serious person," Trump said of Avenatti, adding that he plans to hold both Daniels and Avenatti accountable for paying his legal fees in the actress's recently-dismissed defamation suit against him.

He declined to say whether Attorney General Jeff Sessions will stay on in his position, saying only, "I'm not going to tell you that. We'll see what happens."

And Trump claimed that his administration is working harder than former President Barack Obama's did to prevent foreign interference in U.S. elections.

"I've done more having to do with the new election, the election coming up, than Obama ever did on 2016, ever," he said.

Some experts have questioned Trump's leadership on the issue, arguing that his reluctance to acknowledge Russia's targeting of the 2016 campaign has cast doubt on the effectiveness of his administration's efforts.

On the economy, Trump again criticized Federal Reserve Chairman Jerome Powell for continuing to raise interest rates.

"My biggest threat is the Fed because the Fed is raising rates too fast," Trump said. "And it's independent so I don't speak to them, but I'm not happy with what he's doing because it's going too fast."
