President Obama continued to offer reasons for the United States should take military action in Syria while Republicans discuss Obamacare in their weekly radio and internet addresses today.The president says he's prepared to move forward on a "serious plan" for Syria's chemical weapons but adds that the world must stand ready to act if diplomacy fails.

"We need to see concrete actions to demonstrate that Assad is serious about giving up his chemical weapons," said Obama. "And since this plan emerged only with a credible threat of U.S. military action, we will maintain our military posture in the region to keep the pressure on the Assad regime. And if diplomacy fails, the United States and the international community must remain prepared to act."

Obama says poison gas cannot become the new weapon of choice for tyrants and terrorists.

He blames Syria for an Aug. 21 chemical weapons attack the U.S. maintains killed more than 1,400 people, including children. He threatened a military strike in response but now is awaiting the outcome of negotiations between the U.S. and Russia after Syria agreed to a Russian proposal to turn over the weapons stockpile.

In the Republican address, Tennessee Rep. Diane Black urges the Senate to pass a bill to prevent fraud and abuse in Obama's health care law.

"In an attempt to prop up its struggling health care law, the Obama administration decided they’d hand out subsidies without verifying who’s eligible. They just want to rely on the honor system," said Black, who has proposed the No Subsidies Without Verification Act.  This legislation, according to Black, "stops the government from issuing health care subsidies until it has a system in place to prevent fraud."

The House passed her bill along mostly party lines on Thursday. New Jersey Congressman Frank Pallone spoke against her bill, calling it another Republican attempt to kill Obamacare. ""Your bill will do nothing but prevent millions of hard-working American families from gaining affordable health care coverage,said Pallone.
