Democratic presidential nominee Hillary Clinton criticized her rival Donald Trump for visiting Mexico today, suggesting that it was a “photo op” that lacked genuine leadership.

Citing her experience as Secretary of State, Clinton assured the audience of veterans that she had experience in the “slow hard work” of diplomacy that was required and did “more than a photo op.”

She alluded to Trump’s history of insulting Mexico for over a year, after announcing his run for president.

“People have to get to know that they can count on you, that you won’t say one thing one day and something totally different the next,” she said. “And it certainly takes more than trying to make up for a year of insults and insinuations by dropping in on our neighbors for a few hours and then flying home again.”

Clinton who has repeatedly boasted of her miles traveled as Secretary of State, disapproved of Trump’s decision.

“That is not how it works,” she said, after she was over a half an hour late for her speech.

Clinton cited her experience as a Senator during 9/11, and serving as Secretary of State for President Barack Obama during the Seal Team 6 raid on Osama bin Laden. She did not mention, however, her experience on the day of the Benghazi attacks or the disappointing results of the situation in Libya.
