Deborah Turness, the President of NBC News, released a statement Tuesday night, announcing that the network has chosen to suspend Nightly News anchor Brian Williams for six months, without pay, after he admitted last week that he lied about being on a helicopter that was shot down by RPG fire during the invasion of Iraq in 2003.

According to a report from Politico, the memo from Turness stated that Williams had been notified of his suspension, and that Lester Holt will be his replacement during the suspension:

“We have decided today to suspend Brian Williams as Managing Editor and Anchor of NBC Nightly News for six months. The suspension will be without pay and is effective immediately.  We let Brian know of our decision earlier today. Lester Holt will continue to substitute Anchor the NBC Nightly News.“

Turness then went on to explain that NBC chose to suspend Williams, even though  the internal investigation NBC launched on Friday is still ongoing:

“Our review, which is being led by Richard Esposito working closely with NBCUniversal General Counsel Kim Harris, is ongoing, but I think it is important to take you through our thought process in coming to this decision.

While on Nightly News on Friday, January 30, 2015, Brian misrepresented events which occurred while he was covering the Iraq War in 2003. It then became clear that on other occasions Brian had done the same while telling that story in other venues. This was wrong and completely inappropriate for someone in Brian’s position.

In addition, we have concerns about comments that occurred outside NBC News while Brian was talking about his experiences in the field.

As Managing Editor and Anchor of Nightly News, Brian has a responsibility to be truthful and to uphold the high standards of the news division at all times.

Steve Burke, Pat Fili and I came to this decision together. We felt it would have been wrong to disregard the good work Brian has done and the special relationship he has forged with our viewers over 22 years.  Millions of Americans have turned to him every day, and he has been an important and well-respected part of our organization.

As I’m sure you understand, this was a very hard decision. Certainly there will be those who disagree.  But we believe this suspension is the appropriate and proportionate action.

This has been a difficult time. But NBC News is bigger than this moment. You work so hard and dedicate yourselves each and every day to the important work of bringing trusted, credible news to our audience. Because of you, your loyalty, your dedication, NBC News is an organization we can – and should – all be proud of. We will get through this together.”

Turness concluded the memo by saying that Steve Burke, the President of NBCUniversal had asked her to share this message:

“This has been a painful period for all concerned and we appreciate your patience while we gathered the available facts. By his actions, Brian has jeopardized the trust millions of Americans place in NBC News. His actions are inexcusable and this suspension is severe and appropriate. Brian’s life’s work is delivering the news. I know Brian loves his country, NBC News and his colleagues. He deserves a second chance and we are rooting for him. Brian has shared his deep remorse with me and he is committed to winning back everyone’s trust.”
