He hasn't secured his party's nomination yet, but Donald Trump is already looking ahead to a likely general election matchup with Hillary Clinton.

In a video posted to his Instagram account the day after both he and Clinton took big primary victories, Trump attacked Clinton's credibility on foreign affairs, asking "Is this what we want for a president?"

The video shows a clip of Russian President Vladimir Putin doing judo, followed by images of a masked militant — thought to be a British man named Siddhartha Dhar— with a gun.

"When it comes to facing our toughest opponents, the Democrats have the perfect answer," the text says.

The video shows several seconds of Clinton imitating a dog barking, before cutting to footage of Putin chuckling.

"We don't need to be a punchline," the ad's text says.

Is this what we want for a President? A video posted by Donald J. Trump (@realdonaldtrump) on Mar 16, 2016 at 9:15am PDT

The footage used in Trump's video is from a campaign rally in Reno, Nevada, last month. Clinton was telling a story about fact-checking Republicans and said that it reminded her of a radio ad that she liked where a dog would bark every time a candidate said something false.

"The dog was barking on the radio and so people were barking at each other for days after that," Clinton said. "I want to figure out how we can do that with Republicans."

This isn't the first time Trump has brought up Clinton's barking like a dog. During a South Carolina rally, Trump said he'd never do something like that because he'd be buried in the press.

"If I ever did that, I would be ridiculed all over the place. I won't do it. I'm not going to imitate her," Trump said during a rally in North Augusta, South Carolina. "She's barking like a dog, and they're saying 'wonderful.'"

A spokesman for Clinton's campaign did not respond to a request for comment.

Trump has been criticized for his disparaging language toward women, including prominent figures like Fox News’s Megyn Kelly. An anti-Trump ad released this week shows women repeating various cringe-worthy things the Republican presidential frontrunner has said.
