He repeatedly pointed to White House claims of executive privilege — even though he never worked in the Trump administration.

Lewandowski quickly earned the praise of Trump on Twitter, and used the Capitol Hill appearance to tease a potential Senate run.

During a mid-afternoon break in the hearing, he announced the launch of a new website in a tweet. The site includes photos of Lewandowski and Trump, with the president offering the testimonial “I think Corey would be fantastic” in the Senate.

The House is currently investigating possible obstruction of justice by Trump, who has repeatedly denied the allegations.

Democrats have been divided over whether to support impeachment proceedings against the president, with some hoping that questioning the former Trump campaign aide would help them make a case for it.
