Russia Today reporter Afshin Rattansi asked Mrs May: “Why are you not going to take the 3,000 unaccompanied children from the Calais refugee camp as Jeremy Corbyn and Save the Children said?"
The reporter was blocked by security guards but he continued: "Why won't you answer? Are they a bunch of migrants, like your Prime Minister said?"
Save the Children asked the Government to allow 3,000 unaccompanied children into Britain, something which Mr Cameron has ruled out.
The row over the Prime Minister's words started when had been attempting to brush off the criticism over the Google tax deal which Mr Corbyn said was "derisory".
It comes after it emerged the Internet giant would only pay back £130million in taxes for a 10-year period in which it made £6billion profits in the UK.
Mr Cameron claimed that the Labour leader and shadow chancellor John McDonnell do not stand up to anyone and that they had "met a bunch of migrants in Calais and said they could all come to Britain".
Mr Corbyn this week described the conditions in refugee camps in northern France as "disgraceful" after visiting Dunkirk.
Mr Cameron told him: "All those people filling in their tax returns are going to be paying lower taxes under this Government, that is what's happening.
"And I have to say to you, you can if you want criticise HMRC but HMRC's work is investigated by the National Audit Office and when they did that they found that the settlements that they have reached with companies are fair, that is how it works.
"The shadow chancellor's pointing - the idea that those two right honourable gentlemen would stand up to anyone in this regard is laughable.
"Look at the record over the last week - they met with the unions and they gave them flying pickets.
"They met with the Argentinians, they gave them the Falkland Islands.
"They met with a bunch of migrants in Calais, they said they could all come to Britain.
"The only people they never stand up for are the British people and hard-working taxpayers."
