The White House is asking Congress to approve an additional $30. 1 billion to modernize the nation's aging airports and air traffic control system, citing outdated technology, flight disruptions and safety concerns.

Transportation Secretary Sean Duffy and White House Office of Management and Budget Director Russell Vought outlined the funding request in a letter to lawmakers Friday, urging Congress to act quickly.

By the numbers: More specifically, the Trump administration said it is seeking $10. 1 billion for air traffic control modernization, including $7. 2 billion for a common automation platform and controller workstations and $2 billion for cloud computing.
