Trump administration, politicians and celebrities react to Sean Spicer’s resignation

Spicer said he will continue his service through August.

Spicer called it "an honor and a privilege" to serve the president and said he would stay on through August.

“I am grateful for Sean's work on behalf of the administration and the American people. I wish him continued success as he moves on to other opportunities. Just look at his great television ratings. Sean will continue to serve the administration through August," the statement read.

In an interview Friday with ABC Kansas City affiliate KMBC, political reporter Mike Mahoney said to Vice President Mike Pence that Spicer's resignation "sounds like it's a resignation under protest."

Pence responded, "Well, look: Sean Spicer has been a friend of mine for many years. He is a great guy. He served his country in uniform. And served this administration in our first 6 months. And I respect his decision to step aside. I just wish him every continued success. And we’re just going to continue at this White House and to continue to focus on the agenda that carried President Trump to victory last fall."

Anthony Scaramucci, the new White House communications director, said of Spicer: "He's a military serviceman, he's got a great family, and he's done a great job," adding that "this is a difficult situation to be in and I applaud his efforts."

Comedians weighed in on Twitter, too.

Stephen Colbert, host of "The Late Show" on CBS, chimed in, too. "The fact is, Sean Spicer had the largest group ever to attend a going away party. Period," Colbert tweeted.

Some were already suggesting replacements to fill Spicer’s role.

Others suggested they sympathized with Spicer.

Chandler Thornton, national chairman of the College Republicans National Committee, tweeted that Spicer "has been one of the strongest and most effective advocates" for Trump, adding that he is "grateful for his service in the WH."
