Presidential hopeful Cory Booker on impeachment and child poverty

U.S. Senator Cory Booker says there’s nothing untoward on the side of Joe Biden and his son Hunter -- when it comes to the story of Trump asking Ukraine to investigate Biden. “That this president is trying to change the subject, and he was willing to put national security interests at stake in order to pursue his petty political agenda… It's unacceptable, and if it proves true, then I think it's also an impeachable offense,” Booker says.
