Newt Gingrich: Trump 'won by the act of standing there'

Donald Trump "probably won" the first presidential debate against Hillary Clinton, says Newt Gingrich.

Mr Gingrich, who ran for the presidency in 2012 and supports Mr Trump, tells Today programme presenter Sarah Montague "the very fact that he is her equal" means that is a "legitimate" candidate, which is all that he was required to demonstrate.
