WASHINGTON (AP) - Despite a veto threat from the White House, and opposition from conservatives in their own party, Republicans have pushed through the House a measure that would keep interest rates on millions of federal student loans from doubling this summer.
    
It's a move that has heavy political overtones.

President Barack Obama has been campaigning to keep the loan rates from increasing, but he's threatened to veto this measure because it would be paid for by eliminating a program in his health care overhaul.
