During a Wednesday interview on Fox News, Paul — an opponent of the Senate GOP's healthcare bill in its current form — said all Democrats hate the legislation, and so do half of Republicans.

"The half of Republicans that hate it are conservatives like myself who went to rally after rally after rally saying 'We're going to repeal ObamaCare,' and now we're not repealing it, we're keeping it," Paul said.

"These weak-kneed Republicans up here who are saying, 'Oh, we got to spend more money and we got to keep Medicaid forever, the expansion,' they need to get over themselves."

Paul said Republicans need to remember what they were for: "Repealing ObamaCare."

He added he'd like to support a healthcare bill, but will only vote for one that truly nixes the Affordable Care Act, not just modifies it or scales it back.

Senate leadership on Tuesday decided to delay a vote on their healthcare bill after it became clear it lacked the votes for passage.

Paul has been a vocal opponent of the Senate's bill.

On Tuesday, the Kentucky Republican met with President Trump and said following the meeting that the president is "open to making bill better."
