Factual error: In the scenes of the dinner honoring the President of France, they descend the stairs into the entrance hall and cross towards the State Dining Room. The remaining scenes of the dinner take place in the much larger East Room, completely on the other side of the White House, recognizable from the larger chandeliers and greater size of the room.
Factual error: At the end of the movie the President gives Sydney roses. She asked him how he was able to give a woman flowers while being the President. His response is "it seems I have a rose garden." This was the night of the State of the Union Address. This happens in late January, no roses would be available this time of year from an outdoor garden in January in Washington DC.
