Amid reports of upcoming ICE raids, Sen. Mark Warner defends vote for $4.6 billion border aid bill
Senate Democrats have introduced new legislation that would ban the government from separating families in immigration custody. Virginia Democratic Senator Mark Warner, a co-sponsor of that bill, spoke to CBSN's Reena Ninan about the legislation as well as next week's testimony on the Russia investigation from Robert Mueller. Warner also talked about his new bill that would force companies to disclose how they monetize social media data.
