US President Donald Trump and Chief Justice John Roberts are engaged in an extraordinary public back-and-forth over Trump's description of a judge who ruled against his Administration as an "Obama judge".
Trump tweeted today: "Sorry Chief Justice John Roberts, but you do indeed have 'Obama judges,' and they have a much different point of view than the people who are charged with the safety of our country".
Roberts, in a statement to AP earlier, had pushed back against Trump's description, saying the country doesn't have "Obama judges or Trump judges, Bush judges or Clinton judges".
Roberts said an "independent judiciary is something we should all be thankful for".
Trump says it would "be great if the 9th Circuit was indeed an 'independent judiciary'," but says their rulings are "Very dangerous and unwise!"
