Barack Obama was forced to interrupt a speech when a pregnant woman standing behind him came close to fainting.
The US President was speaking about Obamacare, his controversial healthcare reform programme, in the Rose Garden of the White House when the incident occurred.
He had been talking for 30 minutes when Karmel Allison, who was stood behind him, appeared to become dizzy and came close to keeling over.
Mr Obama became aware of the situation and paused in his speech to turn and aid the distressed woman, saying: "I got you, you're ok.”
As she was helped away by a White House aide, the President joked: “This happens when I talk too long.”
Ms Allison, a biologist from San Diego, California, is pregnant and suffers from type 1 diabetes. She later used her Twitter account to thank Obama for his help.
She wrote: "I'm ok world- just got a little lightheaded. Thanks, @BarackObama for catching me! And good thing this pregnant diabetic is pregnant :)"
She had been invited to the event as a representative of the American Diabetes Association, after writing about the difficulties in finding affordable healthcare.
Her husband David, who was watching the speech, later tweeted his thanks to the President, adding: “I almost bolted to the stage but thought twice about how that would look to the Secret Service.”
However, it didn’t take long for Mr Obama’s detractors to start voicing their skepticism over the incident on Twitter.
“Conspiracy Fun: The woman fainting behind Obama today does kinda seem fake. Why did lady to her right tap her?” asked one.
The President’s speech acknowledged that the roll-out of his signature health care law “hasn’t worked as smoothly as it’s supposed to work”.
He blamed glitches on the Obamacare sign-up website on an overwhelming response, but argued that the Affordable Care Act as a whole is working as planned.
