US President Donald Trump was not at the White House at the time and was spending his weekend at his Florida resort, Mar-a-Lago.
CNN reported that security at the White House was immediately upgraded and there was no confirmation on whether there was any device in the vehicle. Trump was inside the residence at the time. The area is the start of a buffer zone between the main White House fence and the sidewalks.
Jonathan Tran, 26, was in the White House grounds for more than 16 minutes before he was detained.
According to the Daily Beast, a newsletter sent by President Donald Trump's administration featured a story by Washington Post columnist Alexandra Petri and headlined, "Trump's budget makes flawless sense and will fix America, and I will tell you why".
Secret Service supervisors dismissed the gunfire as a gang-related shootout and the bullet holes were not discovered for six days.
The agency said criminal charges were pending.
White House Press Secretary Sean Spicer praised the Secret Service Saturday for their handling of the situation.
On Saturday around 11 p.m., police saw a 2017 Chevrolet Impala with an IN license plate pull up to the vehicle entry bollard.
However, they apparently didn't make it onto White House property.
Another individual was apprehended earlier on Saturday after jumping a barrier in front of the White House, resulting in a full lockdown of the complex.
