The U.S. Secret Service arrested a government contractor on an outstanding attempted murder warrant issued in Maryland when he showed up for work at a White House checkpoint on Tuesday.

The Secret Service says it has no record a reported incident ever happened.

Nothing approximates the scale and the complexity of the White House.

Trump administration has settled on a new director for the agency.

The agent has been placed on administrative leave, the source said.

A Secret Service agent's laptop was stolen with sensitive information and officials discovered the intruder who jumped the White House fence was on the grounds for 16 minutes before being caught.
