Joined my colleague and friend @replindasanchez.bsky.social to discuss the President’s economic policies. Our GDP is shrinking and his tariff war is only hurting businesses and consumers.
Today marks 50 years since the end of the Vietnam War. On this anniversary, we honor all Vietnam War veterans, recognizing their bravery and sacrifice and ensuring their service is not forgotten.
Honored to welcome veterans from the North Bay to Washington today. North Bay Honor Flights provides vets who served in WWII, Korea, & Vietnam the chance to fly to Washington to visit the memorials dedicated to their service. Thanks for all you do to ensure our vets’ sacrifices are never forgotten.
