About 15 people showed up Thursday morning at the Tampa office of Florida Attorney General Pam Bondi to demand an investigation into her alleged ties to a donation from Donald Trump. 

Bondi has faced allegations of bribery and misconduct involving a donation from the Republican presidential candidate.

The Donald J. Trump Foundation sent a $25,000 check just days after Bondi's office told a newspaper that it was reviewing a lawsuit against Trump University filed by Eric Schneiderman, the attorney general of New York. Bondi's office never sued Trump, though she denies his donation played any role in that decision.

On Thursday, the small group of protesters spoke about the need for federal intervention in the case before going inside to the front desk of Bondi's office. Bondi was not in the office at the time.

The call for the federal investigation came the same day that Schneiderman disclosed that his office has been investigating Trump's charity to determine whether it has abided by state laws governing nonprofits.

It was first reported in June that Bondi personally solicited the money during a 2013 phone call that came after her office received complaints from former students claiming they were scammed by Trump's namesake get-rich-quick real estate seminars.

A Democratic Florida congressman, Ted Deutch, is among those calling for a Justice Department investigation.

"If he had no qualms about allegedly throwing money at the judicial system in Florida to make his legal problems go away, it raises a broader question of what kind of president would he be," Deutch said.

The Republican presidential candidate later paid a $2,500 fine over the check from his foundation, because it violated federal law barring charities from making political contributions.

In a letter that all 16 Democrats on the House Judiciary Committee sent Tuesday to U.S. Attorney General Loretta Lynch, ranking member John Conyers of Michigan said federal investigators should determine whether the 2013 donation and Bondi's decision not to join the New York lawsuit violated federal bribery or tax laws.

"This fact pattern indicates that these payments may have influenced Mrs. Bondi's official decision not to participate in litigation against Mr. Trump," Conyers wrote. "A number of criminal statutes would appear to be implicated by this course of conduct."

Bondi has endorsed Trump's presidential bid and has appeared with him this year on the campaign trail.

She has said the timing of Trump's donation was coincidental and that she wasn't personally aware of the consumer complaints her office had received about Trump University and the Trump Institute, a separate Florida business that licensed the Trump name and curriculum.

Meanwhile, the Trump campaign has balked at the attacks, saying it is clearly politically motivated. Bondi has said repeatedly there was no connection between Trump's contribution and her decision not to prosecute.

In addition to a demonstration today, a complaint dated Aug. 22 has been filed with the Hillsborough County State's Attorney to investigate.

Hillsborough County State's Attorney Mark Ober, a Republican, has requested that Gov. Rick Scott select a different state attorney investigator because of his close relationship with Bondi.
