On "America's News HQ" this afternoon, Sen. Rand Paul (R-KY) revealed that another senator confided in him that he was surveilled by the Obama administration.

Earlier this week, Paul said reporters have told him they have evidence he was a target of Obama administration spying.

This is the first time that Paul mentioned another senator is also concerned about the Obama administration's surveillance.

He said if this proves to be true, it's a much bigger story than any allegations about collusion between the Trump campaign and Russia during the presidential election.

"It's about your own government spying on the opposition party," Paul said. "That would be enormous if it's true."

Paul told Fox Business Network’s Charles Payne on Wednesday that he's asked the White House and the House and Senate intelligence committees to investigate.

He said if the intelligence community is indeed being used for politics, it's a "very, very serious crime."

Paul added that the possible illegal use of intelligence community resources for political purposes raises chilling questions.

“They have so much power to collect," Paul said. "I mean, they have the power to collect information, invade your privacy but also to destroy you."
