WASHINGTON (AP) — President Barack Obama will press Congress this week to keep highway and transit aid flowing to states.

The White House says Obama will discuss the issue during remarks Tuesday at a facility in Virginia that tests new technologies for highway transportation. He'll also tout the need to invest in the nation's infrastructure Thursday during a trip to Delaware, where he'll announce an initiative to increase private sector investment.

House and Senate committees took steps last week toward shoring up the federal Highway Trust Fund.

The administration has warned that by early August the fund will no longer have enough money to cover promised aid to states, and the government will begin to stretch out payments. States have been told to expect a 28 percent reduction in aid on average.
