Today, I met Anne, who traveled all the way from Honolulu to speak out against Trump's proposed arch. She's joining many of us later this week to testify before the National Capital Planning Commission's vote. People across the country are standing together to stop this, and we will.

East Potomac Park belongs to the people, not Donald Trump. DC area residents walk here, bike here, golf here, and come here to get outside and enjoy the city. They shouldn't lose a park they love so that Trump and his buddies can have another personal playground.

From crypto schemes to foreign gifts to $330 million for his ballroom, Donald Trump is using the presidency to enrich himself, his family, and his friends. Yet my Republican colleagues are ignoring this blatant corruption while attempting to restrict charitable giving.

A 250-ft arch towering over Arlington National Cemetery would be a sacrilege to those buried there and their families. These men and women served our country honorably. They deserve our respect, not a monument to Donald Trump looming over their final resting place.

Congress foolishly passed legislation granting President Trump expanded tariff powers, hoping he’d use them to help Ukraine. Instead, he’s lifting sanctions on Russian diesel and funneling money into Russia’s economy – money that will help fund its war against Ukraine.

Last year, DOGE cuts cost thousands of federal workers their jobs. Too many are still searching for their next opportunity. These dedicated public servants deserve our support, and I’m grateful to our local partners for helping them get back on their feet.

As AI becomes more capable and widespread, we need a clear regulatory framework for its safe and secure development and deployment. A White House task force can help coordinate federal AI policy, but only Congress can enact durable federal guardrails.

Trump's vanity arch would create a huge mess for everyone trying to get around the area by air or on the ground. It’s a recipe for disaster and I will fight it every step of the way.

When I decided to go back to school to study AI, I did so because I recognized how transformative this technology could be. I’m glad it’s provided me with the expertise necessary to have informed, substantive conversations about how it should be regulated.

DHS violence is out of control. They are shooting people in broad daylight, pointing guns at U.S. citizens, and terrorizing our communities, including right here in Northern Virginia. We owe it to the victims and their families to investigate this misconduct and hold these agents accountable.

Today I joined veterans, preservationists, and concerned citizens demanding that the Administration stop construction of Trump's vanity arch. No one but Trump wants this, so I will not stop fighting against this selfish, dangerous, and illegal proposal until it's gone.

When a law enforcement officer uses deadly force, the agency involved shouldn’t be investigating itself. We need an independent investigation to ensure accountability, transparency, and public trust in the process. That must be the standard for the growing number of DHS misconduct cases.

Since I recorded this interview about the Kennedy Center with Susan Davis, we've learned that the Trump Administration refused to do repairs on the roof, then cited the hazard they created as a reason to justify its closure.

Yesterday, I visited East Potomac Park and saw the golfers, cyclists, runners, and families who enjoy this treasured space. I also saw the Trump Administration tearing apart East Potomac while refusing to tell the public what it is doing, what it has done, or what it plans to do next.

Trump’s arch is illegal and immoral, and the Administration is also under court order requiring 48 hours’ notice before work proceeds. Yet, Trump wants to push ahead without even the most basic understanding of the consequences of this project. We won’t let him.

Don Beyer joins Wolf Blitzer on The Situation Room on CNN to discuss artificial intelligence, returning to school to obtain master's degree in machine learning, and more.
