The man who was arrested after officers found weapons in his car near the White House last week pleaded guilty to reduced charges Monday, NBC News' Pete Williams reported.
R.J. Kapheim, 41, pleaded guilty in D.C. Superior Court to misdemeanor charges of possessing an unregistered firearm and unlawfully possessing ammunition.
Each charge carries a maximum penalty of one year in prison and a fine of up to $2,500. Kapheim will be sentenced on Jan. 26, 2015. He is being held without bond.
Kapheim was expected to enter his plea Friday after reaching a plea agreement with prosecutors, but a scheduling conflict prevented the plea from being heard.
Kapheim had a loaded rifle, a 6-inch blade and 37 rounds of ammunition in his car at 16th Street and Constitution Avenue NW on Wednesday afternoon. According to court documents, he approached a Secret Service officer just before 1 p.m. and said the president had called him and invited him to the White House.
Kapheim was arrested for having an unregistered firearm.
A day and a half after his arrest, a Michigan woman was also taken into custody outside the White House.
April Lenhart, 23, was participating in a demonstration along the north fence line of the White House when two plain clothes agents saw a holstered gun on her hip. She was arrested and charged with possession of an unregistered firearm, possession of unregistered ammunition and carrying a pistol without a license.
The Secret Service has been under scrutiny since a Texas Army veteran, Omar Gonzalez, leapt over a White House fence Sept. 19 and charged into the White House.
Gonzalez made it way all the way into the East Room before he was tackled, due to a string of Secret Service failures detailed in an internal review out last week.
