The passage of our microchip manufacturing bill will put @ASU in the driver’s seat to restore American leadership in microelectronics research and development. ASU President @MichaelCrow understands this. Thank you for your partnership.

Glad to welcome @SecretaryPete to Tucson yesterday to announce investments from our Bipartisan Infrastructure Law that will rebuild the 22nd Street Bridge & support other key projects like this across our state.

As Arizona continues to grow and attract new businesses, our infrastructure must keep up. The bipartisan infrastructure law is already doing that, upgrading roads and bridges, modernizing ports of entry, and expanding access to high-speed internet.

Thank you to @USBPChiefYUM for the tour of the border gaps near the Morelos Dam. Closing these gaps will allow Border Patrol to work more efficiently to better protect Arizonans and keep our borders secure.
Yuma Sector welcomed Arizona Senator Mark Kelly today for a tour of the recently approved Yuma Morelos Dam project. It gives us great pride in helping people understand the successes and challenges our agents in the Yuma Sector encounter each day along the frontlines.

Yesterday, I met with local officials to discuss flood-damaged areas in Flagstaff. Wildfires and flooding have had an impact on residents, and we discussed flood mitigation and fire prevention in Northern Arizona. We have to keep working to protect our communities.

Today, after more than a year of hard work, our landmark microchip manufacturing bill was signed into law! This will provide a boost for Arizona’s economy, lowering costs for families and creating thousands of high-paying jobs, many of which don’t require a four-year degree.

First, it includes our plan to lower prescription drug costs by empowering Medicare to negotiate the price of the most expensive prescription drugs and capping Medicare beneficiaries’ out-of-pocket drug costs at $2,000 per year.

Second, it includes funding we negotiated to combat the impacts of drought and tackles climate change that is making wildfires and heat in our state more severe by boosting renewable energy manufacturing and production.

And finally, it accomplishes these goals without raising taxes on small businesses and middle class Arizonans, and while reducing the deficit, by closing tax loopholes on the most profitable corporations.

When I meet with Arizonans and small businesses across our state, the top concern I hear about is rising costs. This is going to lower costs for health care, prescription drugs, and energy while creating great-paying jobs in Arizona.

The pharmaceutical companies say they’ll go after any senator who votes to lower drug prices for working families. So, here’s a photo of me doing just that last night — because I work for Arizona, not Big Pharma. And no number of political threats will change that.

Lake Mead, Lake Powell, and the Colorado River are facing record-low water levels. Water is our most precious resource. We must act now to secure Arizona’s water future.

This sentence is completely unjust and again demonstrates how Russia has wrongfully detained Brittney Griner. I’ve worked with my colleagues to build support for her release, and am going to ensure that her safe return remains a top priority for the administration.

Prescription drugs should not be unaffordable. Here’s what we need to do: allow Medicare to negotiate lower prices, and cap out of pocket costs for seniors.   Thank you to @kennedydana and @AARPArizona for all of your work on this. Let’s get it done.
Thank you, @SenMarkKelly, for meeting with AARP AZ State Director, @kennedydana, and past State President, Dr. Len Kirschner, to discuss legislation to lower the price of Rx. #FairRxPricesNow
