Q: Rex Tillerson could be on  his  way to serving one of the shortest tenures of any Secretary of State in U.S. history.
âThere are no personnel announcements at this time â White House spokesman Sarah Huckabee Sanders said in a statement. â Secretary Tillerson  continues to lead the State Department and the entire cabinet is focused on completing this incredibly successful first year of President Trumpâs administration.â
âHeâs here.  Rex  is here â he said.
If  Tillerson  leaves in the next few months   he  would likely be viewed as one of the most underperforming secretaries of State in U.S. history with one of the shortest tenures to boot  say experts on American foreign policy.
âIt will ratify what is emerging as almost a consensus view that  Rex Tillerson  was the worst Secretary of State in modern time â said Paul Musgrave  a political science professor at the University of Massachusetts-Amherst who studies American foreign policy. âI actually think there is a good case to be made  ever.â
If  Tillerson  leaves in the next few weeks   he  will have served for roughly a year  inordinately short for a first-term Secretary of State in the modern era. The last three first-term secretaries of State â Warren Christopher  Colin Powell and Hillary Clinton â all remained in their posts for the entire term.
Aside from his short time in office   Tillerson  has little to show as accomplishments.

Q: Billy Bush  is opened up about Matt Lauer's firing and rebuilding  his  life after the fiasco that led to  his  own ouster from the "Today" show in 2016.
 Bush  said  he 's been in touch with  his  former "Today" colleguage Lauer  who was fired by the show after numerous allegations of sexual misconduct in November 2017.
â He  texted me and asked about some of the self-help books Iâve been reading â  Bush  told People magazine. âI told  him   âStart here.â â
 He  said though  he  had a tumultuous relationship with Lauer   he  wasn't happy to see the anchor's scandal unfold.
âMaybe at one point there was part of  me  that [felt like] if someone else got [in trouble]  I would be like  âNow whoâs the bad guy?â â  Bush  said. âBut I took zero pleasure in it. And Iâm grateful for that. Let those who transgressed be held accountable. I felt for the women involved and for his wife.â
The TV personality told People magazine he was displeased with Lauer back in 2016  when "Today" fired  Bush .
On Oct. 7  2016   Bush  was heard on a years-old "Access Hollywood" recording with Trump discussing women in a lewd manner.
"In one of my resolute moments  I said if I ever speak to [Lauer]  Iâm going to tell  him  that I was let down. Many months later   he  called me and I addressed it.  He  assured me that  he  [fought for me] in private. I accepted it.â
"I have done so much self-help work. There is a term for what I did. Itâs called bystander abuse. It says by not doing anything you are endorsing the moment. I have to live with that " said  Bush .
Additionally  the former broadcaster says  he  would never want  his  daughters treated in a degrading manner.
"I have three daughters. They are going to be in the workplace one day. I want them to be paid equally  I want them to be treated well and when they walk out of a room I donât want to ever hear anyone talking behind their back in a degrading way " explained  Bush .
Although   he  has gone through a difficult 15 months  Bush  claims  he  has learned a great deal.
"I had some growing up to do anyway in life " said  Bush . "I did so much exploring and figuring out. Iâm a deeper person. And Iâm happy about using my knowledge for a good purpose.â
