President Trump tweeted that falling gas prices are hurting Russia — proof that he wasn’t working for the Kremlin.

“‘Gas prices drop across the United States because President Trump has deregulated Energy and we are now producing a great deal more oil than ever before.’ @foxandfriends But this is bad news for Russia, why would President Trump do such a thing? Thought he worked for Kremlin?” Trump wrote Monday morning.

The posting comes in response to a New York Times article from Friday that said the FBI opened a secret investigation into whether Trump was working on the behalf of Moscow when he fired former FBI Director James Comey in May 2017.

Trump’s admission that Comey’s dismissal had to do with the Russia investigation, which Comey was overseeing, raised suspicions in the FBI.

Special counsel Robert Mueller, who was appointed just days after Comey’s firing, has taken over the probe.

Trump took to his Twitter feed on Saturday to defend himself against the claims in the report.

In one, Trump called Comey a “Crooked Cop who is being totally protected by his best friend, Bob Mueller, & the 13 Angry Democrats leaking machines who have NO interest in going after the Real Collusion (and much more) by Crooked Hillary Clinton, her Campaign, and the Democratic National Committee. Just Watch!”

He also called in to Jeanine Pirro’s show on Fox Saturday to blast the Times for “the most insulting article.”

“If you ask the folks in Russia, I’ve been tougher on Russia than anybody else, any other … probably any other president, period, but certainly the last three or four presidents,” he told Pirro.
