Columbia University continues to be the epicenter of pro-Palestine protests, with students Tuesday barricading a building. Sen. Marsha Blackburn, R-Tenn., joined "The Hill" to weigh in on what's unfolding at the New York institution. "The leadership of Columbia should step forward and take charge of this," Blackburn said. She said if any of the protesters are foreign students, she would pull their visas and deport them, as well as pull the federal student loans of American students, among other measures. #ColumbiaUniversity #proPalestine #protests "The Hill on NewsNation" combines the power of two trusted news sources to define today's most-pressing issues, and question Washington's power brokers on what matters most to the people they serve and what matters most to Americans.
