The Secret Service is not having a good week. First we learned how easy it was for a man with a knife to run across the lawn and into the White House. And now it turns out that “a security contractor with a gun and three convictions for assault and battery was allowed on an elevator with President Obama.” (At least the guy didn’t enter the elevator before first allowing those inside to exit.)

+ “One intruder in a white karate outfit carried in a knife hidden in a Bible. A stranger slipped in to watch a movie with President Franklin D. Roosevelt. And a pilot crashed his Cessna into the mansion.” The NYT’s Peter Baker takes a look at the ever-expanding list of unwelcome visitors to the White House.
