“But we need a strategy, and I listened to Mr. Kudlow’s interview, I don’t think this administration has a strategy, they don’t have any sense of urgency, and they clearly don’t know what this means to American families.

“Wielding tariffs like a cudgel because it makes the president look tough? That only hurts American families,” Moulton added.

White House economic adviser Larry Kudlow Larry KudlowMORE appeared on the program directly before Moulton to explain the administration's next moves with China.

“You have to have a comprehensive strategy, and I’m not saying tariffs shouldn’t be an option on the table, and that means that we actually build our alliances in the Pacific," Moulton explained. "I am calling for using the NATO model in the Pacific to help contain China and North Korea.

“It means using institutions like the World Trade Organization, now that’s not perfect, it's not going to solve every problem, but every case that the Obama administration has brought before the WTO, every one that’s been decided has been in our favor."

Moulton, one of the over 20 Democrats in the 2020 race, has been touting his focus on foreign policy to try to carve a niche for himself in the crowded field.
