Oh boy. Oh yes it is. You don't bribe someone for information unless you have dirt on them, otherwise there's nothing to stop them turning traitor on you. If you don't have dirt on them, you just invent some. Doesn't matter. People don't fact-check - if the media says it, it must be true.
The CIA typically recruit through a combination of carrot and stick - i.e. bribery and blackmail.
"Hey dude, let me tell you about this sweet slightly dodgy thing I can get you in on."

"Oh by the way, I hope you like all that money you made. I work for the CIA. Work with us or go to jail, your call."
More commonly than not it's not about self-preservation, rather protection of loved ones - read up on Operation Mockingbird, which was driven pretty much entirely on this basis - luring journalists in with a subtle bribe hook, then using it to blackmail them.
