Update 2: British Prime Minister supports Obama’s decision.
I understand and support Barack Obama's position on #Syria.

Update: Obama says he will seek authorization from Congress but reserves right to strike Syria and can do so at any time.
There will be a debate and a vote “as soon as Congress comes back into session”, Obama says.
He says he is “confident” that he has the authority to launch strikes without that authorisation, but says the decision will be stronger with it.
He says the US is primed to strike on Syria.
“The chairman of the joint chiefs has informed me that we are prepared to strike whenever we choose.”
Obama says the chairman has informed him that the military is ready for his order. He says strikes “will be effective tomorrow, next week or one month from now”.
President Barack Obama will give a statement on Syria which is scheduled for 1:15 pm EST. Yesterday Secretary of State John Kerry spoke on Syria with mixed results. The speech comes as the UN inspectors leave Syria and the UK voted to not use military force.
