WASHINGTON (April 14, 2012)--President Barack Obama said Saturday the nation can't afford to keep giving tax cuts to the wealthiest Americans "who don't need them and didn't even ask for them."

Mr. Obama used his weekly radio and Internet address to urge Americans to ask their member of Congress to support the so-called Buffett Rule, which the U.S. Senate is expected to consider on Monday.

The plan would require that people earning at least $1 million annually whether in salary or from investments pay at least 30 percent of their incomes in taxes.

In the Republican address, U.S. Rep. Fred Upton, R-Mich., aid the administration's policies are making gasoline prices worse.

He said Senate Democrats are blocking energy legislation pushed by the House.
