Committee Chairman Jason Chaffetz, R-Utah, is set to meet with acting Secret Service Director William Callahan and Homeland Security Secretary John Kelly about White House security issues on Monday.
The incident followed an earlier one Saturday near the White House. The man had a backpack with two cans of pepper spray and was on the grounds unrestrained for 16 or 17 minutes before Secret Service detained him. On Saturday, a man jumped a bike rack in front of the executive residence, the central building of the White House complex located between the East Wing and West Wing.
Secret Service spokesman Mason Brayman said the agency would release a statement later on Saturday and added he was not aware of any alarms being set off at the White House. "Great response by @SecretService", Spicer tweeted.
At the time of the incident, President Donald Trump was away in his Mar-a-Lago estate in Florida.
The vehicle was being checked, sources told the network. He made his way to the South Portico entrance before being apprehended.
The Secret Service said the unidentified driver was taken into custody after the suspicious vehicle approached a checkpoint.
'It was a troubled person, ' he said about the intruder, whom authorities later identified as Tran.
A Secret Service official speaking on condition of anonymity said the person was not found to be carrying any weapons.
