Trump calls impeachment a "boon" for Republicans
The impeachment proceedings against President Trump will enter a new phase this week, and the president weighed in as he left the White House for a NATO summit in London. He told reporters impeachment would be a "boon" for Republicans and would hurt Democrats in their districts. CBS News political correspondent Ed O'Keefe was at the White House when the president left and joined CBSN to discuss impeachment and the NATO summit.
