The levy is separate from the new tariffs the U.S. imposed on Mexico earlier this year.

Thank you to everyone who made “good trouble” across our district yesterday. Your voice is making a difference, and we need to keep this up. I’ll be with you every step of the way.

Community members line the streets with signs at the Calistoga Good Trouble Protest.

Two people are standing side by side at the Napa Good Trouble Protest, smiling and holding cardboard signs. The person on the left, wearing a white cap and jeans, holds a sign that reads "I'M WITH HIM →". The person on the right, wearing sunglasses and a blue-patterned shirt, holds a sign that says "GOOD TROUBLE LIVES ON". A group of other community members with American flags and signs can be seen in the background.

A woman is smiling on a sunny sidewalk under a tree. The woman wears a straw hat, glasses, a white shirt, and a red, white, and blue scarf. She holds an American flag and is standing with a fluffy cream-colored dog, which also wears a red, white, and blue bandana.
