Republicans aren’t being very vocal about Donald Trump’s statement on listening to a foreign government’s campaign dirt. But Democratic contenders quickly teed off on Trump’s remarks.

Senator Kamala Harris: “China is listening. Russia is listening. North Korea is listening. Let’s speak the truth: this president is a national security threat.” Watch what else she said above.

Senator Bernie Sanders: “We have a president who thinks he is above the law. The House should immediately begin impeachment inquiries.”

Senator Cory Booker: “It’s not “oppo research” — it’s foreign interference in US elections. That you would say this is disgraceful. That you would do it from the Oval Office (yet again) proves you’re unfit for the office you hold.”

Senator Elizabeth Warren: “The made it clear: A foreign government attacked our 2016 elections to support Trump, Trump welcomed that help, and Trump obstructed the investigation. Now, he said he’d do it all over again. It’s time to impeach Donald Trump.”

Senator Amy Klobuchar: “This is inexcusable. The President of the United States just effectively gave permission to foreign agents to interfere in our elections. We need my Secure Elections Act and Honest Ads Act passed immediately. The 2020 elections are not secure. Disgraceful.”

Senator Kirsten Gillibrand: “It’s time for Congress to begin impeachment hearings.”

Julian Castro: “After seeking and receiving the help of our adversaries to to get elected in 2016, Donald Trump is now essentially calling for an open season on our 2020 elections. Once again, he’s putting his interests above our nation’s, and risking and the integrity of our elections.”
