WASHINGTON (AP) -- The "cash for clunkers" rebate program is getting a White House review because it's running so well, and apparently low on cash.
The fear is that the $1 billion set aside to help people replace their gas guzzlers will run out too quickly -- perhaps in just a week.
The White House scotched an earlier report that the program had been suspended, saying only that it's being assessed. It's promising that all valid transactions already made under the program will be honored.
A White House spokesman says they're "evaluating all options" are being considered to keep the program funded.
Under the so-called CARS program, owners of old cars and trucks can get $3,500 or $4,500 toward a new, more fuel-efficient vehicle.
