CNN, MS NOW and Politico denied access to White House

News outlets CNN, MS NOW and Politico on Saturday signaled they would take legal action after their journalists were denied access to the White House grounds earlier in the day. It comes a day after US President Donald Trump announced he would ban the three news outlets from 1600 Pennsylvania Avenue in a row over their coverage of his presidency. Trump has accused the media of "fake news" over their often critical coverage of his second term in office. Experts say the bans conflict with the United States Constitution's First Amendment protections for free speech and press freedom .
