Sen. Ben Sasse (R-NE) signaled he would support a Congressional investigation of senior White House advisor Ivanka Trump’s personal email use during a Tuesday evening interview with CBS’s The Late Show host Stephen Colbert. The Washington Post reported Monday that Trump sent hundreds of emails from a personal email address that she shared with her husband and senior White House advisor Jared Kushner. Peter Mirijanian, a spokesperson for Trump’s attorney Abbe Lowell, said the emails almost exclusively revolved around “logistics and scheduling concerning her family.”
