This man, Bob Kent, looks like he's lying.
He denies that he extorted Matt's father, Don Gaetz, but admits that he "asked" him for $25 million, because "we" needed it (and don't we all need a couple of million?), and his son Matt is in need of some good publicity.
This explanation sound ridiculous. It isn't clear how this $25 million would deliver anything but a (probably fake) video of somebody that could be former FBI agent Robert Levinson, who according to the official (American government) story died while in prison in Iran (if I understand correctly).
It also isn't clear (at least not to me) how this would make Matt Gaetz's legal troubles go away. Or why the Gaetz family would have a special interest in Levinson, paying a cool $25 million.
Bob Kent also explains that he was in contact with the US authorities (including the FBI), who weren't interested in his (fake?) tale.
It could be interesting if Kent would provide evidence that the US authorities aren't interested in rescuing Levinson, but he doesn't...
Former Air Force intelligence officer Bob Kent doesn't even explain what's his interest in Levinson, although he doesn't need to explain why he's interested in $25 million.
I can also understand that former federal prosecutor David McGee, who was hired by the Levinson family, is interested in $25 million. It isn't quite clear why the Levinson family wasn't asked to raise money...
As for a possible story to cover up...
In 2009, the FBI asked Oleg Deripaska (who once hired Paul Manafort) to funnel millions of dollars to Iran, to rescue former FBI agent Robert Levinson, who was captured in Iran in 2007, while working for the CIA.
In 2009, FBI agents courted Deripaska in a series of secret hotel meetings in Paris, Vienna, Budapest and Washington.
One agent who negotiated with Deripaska was Andrew McCabe, fired by president Donald as FBI deputy director. McCabe supposedly played a seminal role in starting the Trump-Russia story.
The FBI rewarded Deripaska for his help. In 2009, Deripaska visited Washington on a rare law enforcement parole visa. Since 2011, Deripaska was granted entry on at least 8 occasions on a diplomatic passport (even though he’s no diplomat).
In 2016, Deripaska was in New York as part of Russia’s UN delegation when 3 FBI agents awakened him.
A couple of months before Trump was elected, they discussed how Russia could get Trump elected:
