Congratulations to MAVA on another successful La Cosecha Grand Tasting event! For the last 13 years, this event has not only brought Mexican-American wineries together for a grand tasting, but has also been a vibrant celebration of Latino culture and our community.

A large, colorful sign spells out "MAVA" on a grassy lawn next to a pond. Each letter is decorated with wine-related images, such as grapes on the "M," a grapevine pattern on the "A," and a bottle and glass on the final "A." A windmill and trees are in the background.

Attendees gather at a tasting table for Aldina Vineyards during the MAVA La Cosecha event. The table is laden with bottles of wine and a large banner with the winery's name and a drawing of a vineyard. The tasting takes place on a lawn in front of a modern building.

It's clear: federal enforcement can't be selective when public safety is at stake. As Chair of the House Gun Violence Prevention Task Force, I will continue to fight back against policies that undermine community safety and encourage open-carry loopholes.

Dangerous hypocrisy on full display. U.S. Attorney Jeanine Pirro, while touting massive weapon seizures and a ‘crime crackdown’ in D.C., has abruptly stopped prosecuting open carry of rifles and shotguns. Yet she continues to brag about taking illegal guns off the streets.

Because of the One Big Ugly Bill, St. Helena Unified had to scrap plans for a solar project. Translation: higher costs for schools, less clean energy for kids’ futures. Ugly indeed.

In July, the Trump administration phased out tax credits for solar and wind projects.
