ABC has filed a lawsuit against the Trump administration’s Federal Communications Commission, alleging violation of its First Amendment rights. Tuesday's lawsuit was a sharp escalation of the network's battle against what it sees as the administration's efforts to police its content. FCC Chairman Brendan Carr has defended his agency’s actions against ABC, saying broadcasters have a duty to “operate in the public interest.”  The FCC launched a review in April of eight ABC-owned broadcast licenses years before they expire. The order came after a joke by ABC late night host Jimmy Kimmel infuriated President Donald Trump.
