A snowy nor'easter bearing down on the East Coast is snarling travel and causing schools to cancel classes.

Heavy snow is also possible in the Appalachian Mountains down to Tennessee and North Carolina.

The UN Secretary General, however, says the European Union's initiative of a "green pact" could make the bloc a world champion to push other big polluters in the same direction. The House impeachment report on President Trump's actions toward Ukraine is being unveiled today behind closed doors for key lawmakers. The report's being made available for committee members to review ahead of a vote Tuesday to send it to the Judiciary Committee for Wednesday's landmark hearing.
