FULL DEBATE: Donald Trump And Hillary Clinton First Presidential Debate (FNN)

Donald Trump is hitting back at Hillary Clinton after she reminded voters watching the first presidential debate that dozens of former Republican national security officials have endorsed her. Trump claims he has the backing of more than 200 former admirals and generals, including scores who have already endorsed him. He suggests the Republicans who have endorsed Clinton are "political hacks." He did not name any of Clinton's backers but argued sarcastically that the "hacks ... have led our country so brilliantly over the last 10 years." He added, "Look at the mess we're in." Hillary Clinton is warning against the spread of cyber-attacks in the United States, particularly from Russia. The Democratic nominee says the United States "is not going to sit idly by" and let hostile nations attempt to hack public or private information. She called out Russia and dinged Donald Trump's frequent praise of Russian President Vladimir Putin. Clinton also criticized Trump for inviting Russia to find her emails. Trump interrupted Clinton, saying "Wrong" when his opponent mentioned his praise of Putin
