WATCH: Jonathan Turley’s full opening statement | Trump’s first impeachment

Jonathan Turley, a George Washington University law professor, cautioned House lawmakers on Dec. 4 against impeaching President Donald Trump. Speaking during the first day of public hearings by the Judiciary Committee in the impeachment inquiry into Trump, Turley said that to impeach Trump based on the current evidence “would be to expose every future president to the same type of inchoate impeachment.” The focus of the Judiciary hearing, which came after the House Intelligence Committee held hearings in late November, is to define the grounds for a presidential impeachment. The impeachment inquiry has revolved around a July 25 phone call in which Trump asked the president of Ukraine to investigate former vice president and 2020 presidential candidate Joe Biden and his son, Hunter.
