The roll call documents a leisure trip from the White House to Trump National Golf Club Washington DC from 9:08 AM to 4:00 PM. Using the benchmark method for a same-day local leisure outing, this is costed as peak off-site Secret Service and staff ($300,000) plus local motorcade transport ($10,000) plus incidentals capped at roughly 15% of travel and security ($50,000), rounded to $360,000.

The evening White House–Mount Vernon–White House trip is documented as a private dinner, but the record here counts only incremental local transport because the day’s off-site leisure/security burden is already captured in the golf outing estimate. A round-trip local motorcade is estimated at $10,000.
