President Trump's top spokeswoman said Tuesday it's a "good move" for GOP Sen. Jeff FlakeJeffrey (Jeff) Lane FlakeLindsey Graham basks in the impeachment spotlight Kelly, McSally virtually tied in Arizona Senate race: poll The Hill's 12:30 Report — Presented by Nareit — White House cheers Republicans for storming impeachment hearing MORE (Ariz.) to not seek reelection. 

“Based on [his] previous statements, and certainly based on the lack of support he has from the people of Arizona, it’s probably a good move," White House press secretary Sarah Huckabee Sanders told reporters. 
 
Sanders derided Flake's speech as "petty," saying his "attacks" on the president were "not befitting of the Senate floor."
 
She spoke after Flake delivered a blistering rebuke of Trump during a speech on the Senate floor announcing his retirement. 
 
In a CNN interview following the White House briefing, Flake said he had "no response at all" to Sanders' comments.

The Arizona senator spoke out soon after Trump attended a so-called unity luncheon with Senate Republicans on Capitol Hill, where he pushed them to get behind a tax overhaul. 
 
 
Sanders pushed back against Corker, who also is not seeking reelection, saying he is “trying to get a headline or two on his way out the door.”
 
"I think the people in Tennessee and Arizona supported this president," the spokeswoman said. "I don't think that the numbers are in the favor of either of those two senators in their states. So this is probably the right decision."
