Barack Obama has told a heckler at an LGBT event at the White House that 'it's not respectful' to heckle someone when invited to their home. 'Hey, listen, you're in my house', the US president tells the heckler, who was protesting against the deportation of migrants to the US. 'You're not going to get a good response from me by interrupting me like this', Obama says to laughs of approval from the crowd, who soon start to chant the president's name
