President Obama will speak to the nation Tuesday as he builds a case for military intervention in Syria.
FOX News Radio's Mike Majchrowitz reports from the White House.
(President Obama) "I knew this was going to be a heavy lift."
President Obama said he had no illusions about the difficulty of convincing Congress to support military action. And with public opinion running against -- the President plans an address to the nation Tuesday night. But he's not predicting a sea change.
(President Obama) "It's conceivable that at the end of the day, I don't persuade a majority of the American people that it's the right thing to do."
And asked if he would act even if Congress votes no -- the President was evasive.
(President Obama) "You're not getting a direct response."
A Senior House Republican official frets the President's Tuesday night address might be too late -- saying this was the critical week to win over public and Congressional support.
At the White House, Mike Majchrowitz, FOX News Radio.
