Mike Bloomberg has been laying low politically following the drubbing he took in his quixotic billion-dollar presidential run, a new report said Tuesday.

In a report on the former mayor’s $20 million investment in Hawkfish, his own digital tech company, a person close to him in the business community told CNBC that Bloomberg was still disappointed in the way his campaign flamed out after spending just over $1 billion of his own money.

The Hawkfish money could be tapped by Joe Biden or other outside groups to go after Trump, but the person said Bloomberg was not yet ready to get back into the public eye of taking on President Trump.

Bloomberg, with a net worth of $54 billion, has been scarcely heard from since transferring $18 million to the Democratic National Committee after dropping out of the race on March 4 after getting creamed on Super Tuesday, the source said.

The $20 million investment went to Hawkfish on March 31 through Bloomberg’s campaign, according to a Federal Election Commission filing, CNBC reported.
