Tucker: 'Unintended Consequences' of Trump-Russia 'Hysteria' Will Be 'Fun to Watch'

Sarah Sanders called out Sen. Bob Corker (R-TN) after he slammed President Trump's foreign policy earlier this week.

Corker accused the president of undermining Secretary of State Rex Tillerson and "raising tensions" in North Korea with his tweets. He suggested Trump "leave it to the professionals" to do something constructive for the country and the world. On Tuesday he remarked that the president "debases" the country.

Trump hit back on Tuesday, saying Corker is opposing tax cuts and "couldn't get elected dog catcher in Tennessee." Later he attacked Corker's record as head of the Foreign Relations Committee, the latest jab in the two's ongoing feud.

"If Bob Corker is suggesting leaving it to the professionals and he's referring to himself, we've left it to him long enough," White House Press Secretary Sanders said. "He's been ineffective and now I think we need to let the president take the lead on this front working with Leader McConnell and others that really want to see some productive change."

"This is a president who wants to be aggressive, who wants to take big action, and if Sen. Corker doesn't want to be part of that I think that's sad for his constituents, but we're not going to let that get in the way of us moving forward," she continued.

Sanders said that there may be "one or two people that don't want to see the ball move further down the field" on tax reform, fixing the Iran deal, and putting pressure on North Korea, but she hopes Sen. Corker is the only one.

President Trump will have lunch with several senators including Corker today.
