'Utterly unthruthful' - Republican senator on Trump

Influential Republican Senator Bob Corker has unleashed a blistering attack on US President Donald Trump, calling him "utterly untruthful". In a series of television interviews, Mr Corker accused the president of lying, adding that he debased the US and weakened its global standing. Mr Trump fired back on Twitter, calling the Tennessee senator a "lightweight" who "couldn't get elected dog catcher in Tennessee". Washington correspondent Kevin McAleese says Mr Corker was an early supporter of Mr Trump but not any more.
