NEW YORK – At the end of Donald Trump's presidency, television networks left the mute button unused.They covered Trump's farewell address at Joint Base Andrews, the opening event of a most unusual inauguration day, from beginning to end without pulling away — a possibility that MSNBC's Joe Scarborough raised as the outgoing president began to talk.“We're going to dip into this for as long as the president manages to tell the truth,” Scarborough said.His network, along with ABC, CBS, CNN, Fox News and NBC, did not pull away.
