Ernst: House Could Have Brought in Bolton and Didn't, 'Investigative Work' Is 'Not the Job of the Senate'

On Monday's "Hugh Hewitt Show," Sen. Joni Ernst (R-IA) stated that while she won't make a final judgment on which witnesses, if any, she wants to call in the Senate's impeachment trial, doing "investigative work" is not the Senate's job, and the House had the opportunity to bring in former National Security Adviser John Bolton as a witness and didn't.
