Sen. John CornynJohn CornynDemocrats up ante in risky debt ceiling fight Senate parliamentarian nixes Democrats' immigration plan Democrats make case to Senate parliamentarian for 8 million green cards MORE (R-Texas) in a Sunday interview said President Trump has “created problems for himself” with his "Twitter habit."
“Unfortunately the president has, I think, created problems for himself by his Twitter habit,” Cornyn said in an interview with WFAA-TV.
The senator also said the president's agenda has suffered "because he hasn’t been able to assemble a team around him at the departments like the State Department, the Defense Department, because of slow heel-dragging by the Democrats.”
Trump regularly uses his personal Twitter to discuss official business, with his tweets functioning as statement from the president.
Following reports of the attacks in London Saturday night, for example, Trump on Twitter emphasized the need for his “Travel Ban as an extra level of safety!"
Cornyn, the Senate majority whip, gave Trump a B+ in the interview for his handling of foreign policy issues since taking office.
“He enforced the red line on Syrian chemical weapons. He enlisted China to help with North Korea — I think the pre-eminent threat to us right now. I think he has shown some mettle in dealing with Russia and Putin particularly in dealing with Syria and around the world,” Cornyn said.
