Democrats said the Senate parliamentarian ruled against including $1 billion for White House ballroom-linked security in a budget bill under reconciliation rules. Sources indicate the ruling may force changes or a 60-vote threshold. GOP aides indicated efforts to rework the plan post-ruling. Three aides noted that lawmakers must find another path to authorize construction of the White House ballroom. Democrats cast the ruling as a setback for the Trump agenda. Supporters noted the ruling clarifies budget-rule boundaries. The ruling reached lawmakers and staff late Saturday night. Observers noted the balloting path remains unclear without changes. Party leaders pursued a path to keep the plan alive while respecting rules.
