Rep. Gaetz's ex-girlfriend spotted entering Florida courthouse where grand jury is meeting

Rep. Matt Gaetz's ex-girlfriend was seen entering a courthouse where sources say a grand jury is conducting a sex trafficking investigation involving the congressman.

A former girlfriend of Florida Rep. Matt Gaetz, who is potentially a key witness in the ongoing federal sex trafficking investigation into the congressman, was spotted on Wednesday with her lawyer entering an Orlando federal courthouse where a grand jury has been meeting, according to a source.

The ex-girlfriend, who ABC News is not naming, could play a crucial role for investigators who are continuing to probe Gaetz's alleged sexual conduct with a separate young woman who was 17 years old at the time.

Gaetz's former girlfriend allegedly has knowledge not only regarding the congressman but also the one-time minor at the center of the sex trafficking investigation, sources said.

The ex-girlfriend, who previously worked on Capitol Hill, was also one of the women who was allegedly on a 2018 trip to the Bahamas with Gaetz and others, including the 17-year-old, which prosecutors are also investigating, according to legal sources familiar with the case.
