Sen. Bob Corker, R-Tenn., shot back at those criticizing him for agreeing to vote for the GOP tax bill he previously opposed.

“I know that I'm being maligned over totally malicious stuff that has totally been disproven,” Corker told CNN host Wolf Blitzer Tuesday. “I know people are having a good time with this but it's just malicious. I'm making this decision because I believe that it is best for the country. Period.”

Reports emerged days ago that a provision had been included into the plan that would possibly benefit owners of income-producing real estate — such as Corker and President Trump.

Corker opposed the initial version of the bill but announced on Friday that he would support the newest one after it went through the Senate-House conference process.

Earlier in the interview, Corker pushed back on allegations that his vote had changed due to the last-minute inclusion of the real estate provision.

“First of all, I knew nothing about the provision. I've had no involvement,” Corker said. “It actually came out of the House. It was part of their House bill when they did the reconciliation. It was merged in and altered slightly to make it conform.”

The House will be voting on the GOP tax plan again on Wednesday after the Senate was required to change certain parts of the bill to clear a parliamentary hurdle.

The Senate is expected to pass a slightly modified version of the bill Tuesday evening.

Corker has been an outspoken critic of Trump and announced earlier this year he will not be seeking reelection in 2018.
