Sen. Lindsey Graham took to Twitter Thursday morning to blast Trump for making American “less safe” with his comments about refusing to abide by NATO treaties.

The GOP nominee for President is essentially telling Russians/other bad actors the US is not fully committed to supporting NATO alliance.

#2 — NATO has been the most successful organization in modern history to provide collective defense for democracies.

Statements like these make the world more dangerous and the United States less safe. https://t.co/8hrywK6wEM

#4 — I can only imagine how our allies in NATO, particularly the Baltic states, must feel after reading these comments from Mr. Trump.

#5 — . I’m 100 percent certain how Russian President Putin feels – he’s a very happy man.

#6 — Mr. Trump has shown the ability to correct statements such as this. I hope he will do so tonight when the world is watching.

Graham made national security the cornerstone of his unsuccessful bid for the GOP nomination and has been one of Trump’s most consistently harsh Republican critics, even going so far as to ask party members to un-endorse him.
