WASHINGTON (December 8, 20120--President Barack Obama continued a relentless push for his middle class tax cut plan in his weekly media message for the fourth time since his re-election.

Mr. Obama accuses House Republicans of blocking a bill that would prevent a tax increase on the first $250,000 of income earned by all Americans.

The Democratic-controlled Senate has approved the measure.

Mr. Obama said a House bill is unbalanced and actually lowers rates for the wealthiest Americans, instead of raising them as the president has proposed.

For the GOP, Florida Sen. Marco Rubio says tax increases will not solve the nation's $16 trillion debt.

He said the only way to do that is through economic growth and reform of entitlement programs.

He says limited government can help meet the challenge of restoring the middle class.
