A federal grand jury has hit former Florida Democratic gubernatorial candidate Andrew Gillum with a subpoena, reportedly seeking information regarding his 2018 campaign.

Here's what we know

While Gillum was mayor of Tallahassee, the city government (but not — as Gillum frequently pointed out — Gillum himself) was the subject of an FBI investigation. In January, the Florida Ethics Commission did determine that there was probable cause that Gillum had failed to report gifts he had accepted from lobbyists and vendors while he was mayor.

Gillum settled with the Ethics Commission in April and agreed to pay a $5,000 fine. Questions about Gillum's interactions with an undercover FBI agent also dogged his campaign.

The Tampa Bay Times obtained a copy of the subpoena, which was issued on March 26. It reported that along with records dating back to the beginning of 2015, the subpoena also demanded records related to both Gillum's gubernatorial campaign and his political action committee.

It is not clear what specifically the grand jury is investigating, but the Times said that while the subpoena focuses on "people and organizations with clear ties" to Gillum, they have "less obvious connections to Tallahassee City Hall." This could indicate that it is not related to the previous investigation into corruption in the Tallahassee city government.

After his loss in November 2018 to current Republican Gov. Ron DeSantis, CNN hired Gillum as a contributor.

What did Gillum say?

For now, Gillum has not weighed in on the details of the recent subpoena.

"We stand ready to assist any future review of our work, because I am confident we always did the right thing and complied fully with the law," he told the Times in a statement.

Gillum added that he had run an "open and honest campaign" and said "[w]hen you run a campaign that puts the power in the hands of the people, and fights for change, it inevitably invites close scrutiny, regardless of the facts."
