President Obama is making his case for a strike against Syria. He told PBS Newshour Syrian President Bashar Assad is responsible for last week's deadly chemical attack on civilians near Damascus.
"We have concluded that, the Syrian government in fact carried these out, and if that's so, there needs to be international consequences."
The President also confirmed any U.S. military action would be a brief and surgical strike.
"I have no interest in any kind of open-ended conflict in Syria."
Thursday the White House is briefing select members of Congress on intelligence linking the Assad regime to the chemical weapons attack.. and also preparing an unclassified public report.
Britain's government released its version of those documents Thursday while Prime Minister David Cameron tried to get Parliament on board.
""In the end no 100 percent certainty who is responsible, but you have to make a judgment," he said.
U.S. intelligence officials say the case against Assad isn't a slam dunk, but some lawmakers are already convinced the U.S. should act.
"The use of chemical weapons in violation of international law against innocent civilians is something that can not stand," said Sen. Robert Menendez, D-NJ.
The United Nations Secretary General is urging the US and its allies to hold off any military response until UN investigators finish their report. The team is set to leave Syria Saturday.
More than 100 House members signed a letter demanding President Obama seek authorization before taking any military action.
