When it comes to following Democratic Party leaders who are critical of President Donald Trump’s strategy for rapprochement with North Korea, Rep. Ro Khanna is diverting from a growing party othodoxy.

U.S. Sens. Chuck Schumer, Dianne Feinstein and five other senate Democratic leaders sent a letter to Trump last week opposing the easing of sanctions against North Korea unless a list of stringent conditions were met, including denuclearization.

Khanna’s response was blunt, tweeting last week, “Let me be clear @SenSchumer does not speak for the Democratic Party concerning North Korea and Iran.”

The same day New York Times columnist Nick Kristoff offered a similar critique of Senate Democrats, writing, “Trump’s newfound pragmatism is infinitely preferable to the threat of nuclear war that used to hang over all of us, so it’s mystifying to see Democrats carping about any possible North Korea deal.”

Khanna, using his congressional campaign Twitter handle, retweeted the column and again undermined Schumer, calling him “simply wrong on this issue.”

On Monday, as Trump and North Korean dictator Kim Jong Un met for a summit in Singapore, Khanna appeared before the Korea Peace Network. According to a tweet from a person in attendance, Khanna told the group, “The role of Democrats should be encouraging dialogue.”
