Democrats said the Senate parliamentarian ruled against including $1 billion for White House ballroom-linked security in a budget bill under reconciliation rules. Officials say the decision could trigger modifications or a 60-vote requirement. Republicans said they would revise the proposal after the ruling. Three aides noted that lawmakers must find another path to authorize construction of the White House ballroom. Democrats framed the ruling as a setback for Trump and his administration. Supporters argued the ruling underscores reconciliation constraints. The ruling reached lawmakers and staff late Saturday night. Observers caution that the path ahead is uncertain without revisions. Party leaders pursued a path to keep the plan alive while respecting rules.
