As a Catholic, I find it abhorrent that the President of the United States would publicly attack the Successor of St. Peter. Donald Trump is flailing. His war in Iran has led to the death and injur...
Today is International Day of Human Space Flight, a fitting way to cap off a historic week. This year, we have a lot to celebrate. Four astronauts went further than ever before to help pave the...
Yesterday, the crew of Artemis II splashed down off the coast of California, capping off a historic 10-day journey to the Moon and back. This mission did something remarkable: It captured the worl...
Artemis II is home. What this crew accomplished, with the help of thousands and thousands more on the ground, is going to matter for a long time. This is how we build toward landing on the Moon and...
This was an extremely complex mission, but NASA and the crew of Artemis II made this look easy. They did a really great job, and everyone involved should be incredibly proud. https://t.co/dJagdjSLPI
Arizonans are working hard and still struggling to pay for groceries, rent, and health care. Here's the thing—this didn't happen by accident. Trump and Washington Republicans had a choice and t...
In the middle of a historic mission back to the Moon, this Administration is proposing to a 47% cut to NASA science and a 23% cut to NASA’s budget overall. Last week’s launch showed our country and...
In 1960s, the Apollo missions gave people something to believe in. We could use that right now. And I think Artemis II is it. https://t.co/wT7cu9kFrj

Foreign companies are now giving Trump donations for his ballroom at the White House. And in return at least one got a break on tariffs. Not only is his ballroom a ridiculous distraction, it's just...

Somewhere out there a kid is watching this mission who might be inspired to study science and engineering and one day be the first person to walk on another planet. That's one of the reasons wh...
Arizona’s impact has been felt on the Moon. That’s true for the Artemis missions, and it was true back on the Apollo missions. Pretty good track record. https://t.co/4KxJr7zqmE
In Phoenix today to hear from food truck and small business owners. Fuel, food, supplies. Prices are up across the board and it's squeezing Arizonans. I'm focused on bringing down costs, because i...
Great crowd and discussion at the Tucson Rotary Club today. The cost of living is top of mind for a lot of Arizonans right now and the war with Iran has only made it worse. I’m working hard to br...
