FBI director open to investigating Trump's claim on forged signature in Epstein book

Driving the news: Jared Moskowitz (D-Fla.) started the line of questioning during Patel's Wednesday House testimony, but Patel did not go on record calling the signature fake.

• "Will you be opening up an investigation into the Epstein estate for putting out a fake document with the president's signature linking him to the world's largest pedophile ring?" Moskowitz asked.
• "On what basis?" Patel responded.
• "On what basis? They literally put out a fake document, according to the president, with a fake signature. It's a forgery of the president of the United States' signature," Moskowitz said.
• "Sure, I'll do it," Patel said.
• The dialogue finished with Moskowitz saying he looks forward to the investigation.

Context: House Democrats earlier this month released a note that Trump allegedly wrote in a birthday book for Epstein, a convicted sex offender, in 2003 with a lewd drawing of the outline of a woman's body.

• The White House claimed that the president's signature was fake because it didn't match his recent autographs.

Yes, but: Analyses showed that Trump's signature matched the style of several hand-written, personal letters he penned throughout the 1990s and 2000s.
