US President Barack Obama has been heckled while giving a speech at the White House.

He and Vice President Joe Biden had welcomed a group of lesbian, gay and transgender people to a reception.

Mr Obama addressed the upcoming Supreme Court decision on same-sex marriage.

But an immigration campaigner would not stop interrupting him.

"Not one more deportation!" the person shouted, before being escorted from the room by Secret Service agents.

Mr Obama appeared angry at the interruption and addressed the protester directly.

"No, no, no. Listen, you're in my house...It's not respectful...you're not going to get a good response from me by interrupting me like this."

"Shame on you. You shouldn't be doing this", the president said, to which the crowd replied with chants of 'Obama! Obama!'.

"You can either stay and be quiet or we'll have to take you out", Mr Obama added.

When it was all over, one man from the crowd shouted "we love you!" - to which the president replied: "I love you, back".
