Former Democratic presidential nominee Hillary Clinton Hillary Diane Rodham ClintonBiden courts veterans amid fallout from Trump military controversies Biden looks to shore up Latino support in Florida MLB owner: It's 'very necessary' to vote for Trump MORE on Tuesday indirectly criticized President Trump for his early-morning Twitter habit.

Speaking with CNN's Christiane Amanpour at a Women for Women International event, Clinton said negotiations must be coupled with a broad strategy on issues like North Korean aggression that cannot be expressed in short tweets.

“Negotiations are critical, but they have to be part of a broader strategy, not just thrown up on a tweet some morning that, ‘Hey let’s get together and, you know, see if we can get along and maybe we can come up with some sort of a deal.’ That doesn’t work,” Clinton said.

Clinton also said that she'd prefer that Trump tweet about her instead of foreign affairs.

"I'm happy to be the diversion," she said. "We've got lots of other things to worry about. He should worry less about the election — and my winning the popular vote — than doing some other things that would be important for the country."

Trump frequently tweets early in the morning from his personal Twitter account.

Clinton said during the interview that she supported Trump’s decision to conduct a military strike against Syria in response to a chemical attack allegedly carried out by forces loyal to Syrian President Bashar Assad. But the former secretary of State said it’s “too soon to really tell” whether or not the strike will be effective.

“I am not convinced that it really made much of a difference, and I don’t know what kind of potentially backroom deals were made with the Russians,” Clinton told Amanpour.

“And if all it was was a one-off effort, it’s not going to have much of a lasting effect.”
