Police arrest a 21-year-old man on Wednesday - suspected of shooting at the White House last week.
Officials said Oscar Ortega-Hernandez was picked up by troopers at a hotel near Indiana, Pennsylvania - about a four-hours drive from Washington.
Earlier in the day, U.S. Secret Service had said federal agents found two bullets hit the mansion after Friday's shooting.
One struck a protective window and another struck the building's exterior.
No one was hurt in the incident - and President Barack Obama and First Lady Michelle were not in the building.
The shooting is under investigation.
