Billionaire presidential candidate Michael Bloomberg requested an extension on keeping the details of his fortune secret until after millions of voters have participated in the 2020 Democratic primaries.

Bloomberg received an extended deadline to file his financial disclosure form more than two weeks after Super Tuesday, the New York Times reported.

The former New York City mayor, who is worth an estimated $50 billion, entered the race in November, months after his Democratic rivals.

Bloomberg and Tom Steyer, another billionaire running for the nomination, have been accused of using their wealth to buy the nomination. Bloomberg, 77, has already poured more than $200 million into television and digital ads in the past two months.

If Bloomberg were to end his candidacy before March 20, he could exit the race without having to make any financial disclosures.

His campaign previously said he would release his tax returns but has not said when or how many years he’d disclose.
