BP's $20 billion escrow fund is a "PR stunt" that came about through a "suspicious" process, Rep. Ron Paul (R-Texas) said Tuesday night.

Though Paul didn't go as far as fellow Texan Rep. Joe Barton (R), who called the fund a "shakedown," he nevertheless said the "process is sort of suspicious."

"They have agreed to this and this is sort of a PR stunt as far as I'm concerned," Paul told Fox News. "BP had already been making a lot of payments to people who had been injured."

Paul emphasized that he wants BP to pay for all the damage they've caused, but said he was wary of government pressure on the corporation.

"I think they should pay. There are legal ways of doing this, but I'm very suspicious of how this has come about," he said.
