Democrats release 2024 presidential campaign autopsy; Republicans could abandon $1bn proposal for Trump’s ballroom – live

President Donald Trump’s plan to build a triumphal arch in Washington is getting a second look from a federal agency that suggested changes before it approved the concept last month.

The proposed 250ft (76m) arch is one of several projects the Republican president is pursuing alongside a White House ballroom to leave his imprint on Washington.

He has said some of his other projects, such as adding a blue coating to the interior of the Lincoln Memorial Reflecting Pool , will beautify the city in time for 4 July celebrations of America’s 250th birthday.

The US Commission of Fine Arts, whose members were appointed by Trump, approved the concept for the arch at its monthly meeting in April.

Commissioners are set to consider and possibly vote on updated plans when they meet again on Thursday.

A prominent environmental organizer calling for a nationwide moratorium on data centers as he runs for the Democratic nomination in a swing Michigan congressional district has secured an endorsement from Bernie Sanders.

Will Lawrence, co-founder of the youth-led Sunrise Movement climate justice group, was a key figure behind the campaign for a Green New Deal to battle economic and racial injustice while also fighting climate change.

Now he’s running for US Congress, in a three-way Democratic primary to represent the party in Michigan’s purple seventh district.

“I learned at Sunrise just how important it is who is in office,” Lawrence, a Lansing native, said. The group made headlines in 2018 when it stormed the office of then House of Representatives speaker Nancy Pelosi, demanding a swift end to fossil fuels and a jobs guarantee.

Voters in Michigan’s seventh district voted for Donald Trump in the 2016, 2020 and 2024 US presidential elections, and also elected Republican Tom Barrett to Congress in 2024. But the district has been labelled a “toss-up” by the Cook Political Report ahead of November’s midterm elections, and is a key target for Democrats.

On Thursday morning Sanders, the influential independent US senator from Vermont, threw his support behind Lawrence.

In a statement, Sanders praised Lawrence as an “accomplished organizer” who will “demand real accountability for big tech and AI companies” as gargantuan data centers are constructed across the US.

Senate Republicans could strip Donald Trump’s lavish White House ballroom complex from the Department of Homeland Security funding bill after members queried the timing and lack of detail in the $1bn Secret Service request.

Facing pressure from the Trump administation, Republicans have tried to add the money to a roughly $70bn bill to restore funding to US Immigration and Customs Enforcement and the Border Patrol.

However, the security proposal met with backlash from some GOP lawmakers who are questioning the cost and how the taxpayer dollars would be used, AP reported. While the bill’s text has yet to be released, the Senate hopes to pass it this week and send it to the House before leaving for a week-long Memorial Day recess.

The dispute comes as Senate majority leader John Thune acknowledged “ongoing vote issues” on Wednesday with leaders attempting to measure Republican support, as well as “ongoing parliamentarian issues” as they try to figure out what will be allowed in the bill under the chamber’s rules.

“There’s always a consequence with taking on United States senators,” Thune said. “[The president] obviously has his favorites and people he wants to endorse and that’s his prerogative. But what we have to deal with up here is moving the agenda, and obviously that can become slightly more complicated.”

Republican senator John Kennedy said on Wednesday that the bill would be “back to square one” without the security money because “the votes are not there.”

Meanwhile, senator Thom Tillis said the effort to add the security package to the bill was a “bad idea” because he does not think there is enough backing to pass it, even if the cost were reduced. Axios reported recently that Tillis would not support the bill if it is considered this week.

Democrats have criticized Republicans for trying to fund Trump’s ballroom when voters are concerned about basic affordability issues.

• Republican senator Bill Cassidy denounced two of Trump’s passion projects: $1bn in taxpayer funding for the White House ballroom the president can’t stop talking about, and the $1.776bn slush fund he plans to use to reward supporters who stormed the Capitol to try to keep him in office despite losing the 2020 election.
