Why is President Trump endorsing the House budget proposal and what significance does it hold?

President Trump endorsed the House budget proposal amid an ongoing budget battle between House and Senate Republicans. In his social media post, Trump emphasized that the House resolution implements his "full America first agenda, everything, not just parts of it." Trump's endorsement is strategically important as he stressed the need for both chambers to pass the House budget to initiate the reconciliation process, which is crucial for advancing his policy agenda. This support comes as the two chambers are pushing separate budget blueprints, highlighting Trump's alignment with the House version in the months-long Republican budget dispute.
