WASHINGTON — President Donald Trump has been uncharacteristically quiet on Michael Bloomberg, declining to publicly attack the media mogul since the Democrat launched his White House bid last month.

Trump has not mentioned Bloomberg at rallies, where he regularly derides Democratic presidential candidates Joe Biden, Elizabeth Warren, Bernie Sanders and Pete Buttigieg with zeal.

Trump’s campaign says it is unfazed by the billionaire, who has spent $100 million of his own money on advertising and voter registration efforts for a relatively late entry in the race for the Democratic nomination. That amount does not include other campaign spending such as on staff, travel and offices since Bloomberg entered the race in November after saying earlier in the year that he would not compete in 2020.

“At this point in the game, I don’t know that you recover from that. He hasn’t been in any debates, people haven’t really heard much from him,” said Lara Trump, a senior adviser to the president’s re-election campaign and his daughter-in-law. “While he does have a lot of money to spend, so do we. We have a ton of money at the Trump campaign.”

The Republican National Committee and the Trump campaign raised $125 million in the third quarter of 2019. Bloomberg’s fundraising will not be revealed until next week, when every presidential candidate is required to file a year-end report. However, the candidate said he will reject political donations and will self-fund his campaign.

The former New York City mayor — currently has a net worth of $55.9 billion. According to Forbes, Bloomberg is the eighth wealthiest American. Donald Trump ranks 275th on the list with a projected net worth of $3.7 billion.

Republicans close to the national party told McClatchy that when Bloomberg was preparing to enter the race they worried the self-made billionaire would get under Trump’s skin.

But Tim Murtaugh, a Trump campaign spokesman, told McClatchy in a statement, “We don’t spend a lot of time thinking about Mike Bloomberg.”

Bloomberg spokesman Michael Frazier, in an email to McClatchy, responded, “The Trump campaign has a funny way of showing they aren’t thinking about Mike. Maybe they can explain why they’ve criticized each of our office openings in battleground states, or why their campaign manager banned Bloomberg News from their events?”

After Bloomberg entered the race, the Trump campaign said it would no longer give credentials to reporters who work for Bloomberg News, although none of them have been prevented from attending his rallies so far.
