It's also widely believed that is a big part of why he vetoed a bill to fund the Arkansas River Valley water pipeline in Colorado, to bring much needed clean drinking water to rural communities in southeastern Colorado (communities that overwhelming voted for Trump all three times).

Another reason widely believed to be a significant factor is that it would benefit Lauren Boebert's district, and Trump wanted to punish her for siding with Democrats in the House on releasing the Epstein files.

The pipeline funding bill had been very bipartisan. It had passed the House by unanimous consent, and whatever the equivalent procedure is in the Senate.

There was an attempt to override the veto. The House vote was 248-177, which failed because a veto override requires 2/3 of the votes. It would have needed 283. All Democrats voted to override. It would have taken 71 Republicans to push it over, which would have been 1/3 of Republicans present. It only got 35, 1/6th of the Republicans.
