The Secret Service says a man interfered with a motorcade carrying Republican presidential nominee Mitt Romney as his vehicle arrived at a secure checkpoint near the White House. The man was later arrested after he became combative during an interview with a police officer.

Secret Service spokesman Max Milien says the man, who was not identified, was standing near a security entrance to the White House and got in the motorcade�s way. The vehicle stopped briefly at the security gate and then entered the White House complex.

Milien says the man was later interviewed by a uniform division officer and became combative. He was charged with assault on a police officer and unlawful entry.

Romney came to the White House for lunch with Obama, their first meeting since the election.
