Sen. Bob CorkerRobert (Bob) Phillips CorkerCheney set to be face of anti-Trump GOP How leaving Afghanistan cancels our post-9/11 use of force The unflappable Liz Cheney: Why Trump Republicans have struggled to crush her  MORE (R-Tenn.) on Monday said it's "best to refrain from communicating with 140 characters," after President Trump used Twitter to criticize the mayor of London in the wake of a terrorist attack there. 

"We live in a world today where unfortunately a lot of communication is taking place with 140 characters. Probably it's best to refrain from communicating with 140 characters on topics that are so important," said Corker, who is chairman of the Foreign Relations Committee, when asked about the president's tweets. 
Trump sparked backlash after he used Twitter to criticize London Mayor Sadiq Khan, writing, "At least 7 dead and 48 wounded in terror attack and Mayor of London says there is 'no reason to be alarmed.' " 
Trump doubled down on his comments on Monday morning, saying Khan had a "pathetic excuse." 
Trump's tweets appear to take Khan out of context. The London mayor said on Sunday "my message to Londoners and visitors to our great city is to be calm and vigilant today. You will see an increased police presence today, including armed officers and uniformed officers. There is no reason to be alarmed by this." 
GOP senators have repeatedly questioned, if not criticized, Trump's penchant for tweeting controversial statements, which lawmakers are frequently asked about on Capitol Hill. 
Corker added that he had a discussion within his office about "multiple communications" earlier on Monday and that he wasn't aware of Trump doubling down on his criticism of Khan until after that. 
The GOP senator didn't specifically criticize Trump and also argued that some news on Twitter is frequently packed in "superficial headline-like material." 
"It's also, you know, a shame that so much of the communication that's taking place between folks today is occurring with 140 characters. ... I think it would be much better actually if all of us would communicate in a different way than using 140 characters," he said. 
Corker has walked a fine line with the Trump administration. He was considered for secretary of State and went golfing with Trump on Sunday. While he's tried to give the administration time to work out its foreign policy, he's also voiced frustration with a string of controversies coming out of the White House. 
He clarified on Monday evening that he isn't walking back "one inch" of a previous comment about how his statements to reporters are sometimes directed at the White House. 
"While they're said to the public, they're meant to influence things that are happening within the White House itself," he told reporters. "I use every mechanism available to me to try to influence what's happening within the White House and who's being listened to within the White House, and that's why sometimes these comments might be hard for the public to understand."
