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: Olympic gold medalist Aly Raisman has stripped down for Sports Illustrated's Swimsuit issue.
The move comes after  Raisman  made headlines recently for presenting a powerful 13-minute testimony against Larry Nassar during which she directly told the former Olympic doctor  âYou are nothing."
âI would like to remind everyone that being a survivor is nothing to be ashamed of  and going through a hard time does not define you â  Raisman  said to SI Swim. âI hope that we can one day get to a point where everyone realizes that women do not have to be modest to be respected. We are free to draw confidence and happiness in our own way  and it is never for someone else to choose for us or to even judge us for that matter.â
âFor me  âIn Her Own Wordsâ serves as a reminder that we are all humans  we are all battling something  and it is OK to not be OK â  Raisman  said. âWe are not alone and we need each other.â
âYou lose a part of yourself when youâre abused â  Raisman  recently told People. âI lost a part of myself  and Iâm getting it back by speaking out.â

A: Aly Raisman

Q: Gen. Mohammad Ali Jafari  head of Iranâs Islamic Revolutionary Guard Corps   added that Iran had the capability to expand its missile range beyond that limit  the Washington Free Beacon reported  citing information from U.S. officials and regional reports.
The comments by  Jafari  appeared to be an effort by Iranian authorities to contrast their missile program  which they often describe as being for defensive purposes  against those of countries like North Korea  which has talked about launching missiles that can hit any U.S. city.
Speaking on the sidelines of a conference in Tehran   Jafari  told journalists that the capability of Iran's ballistic missiles was "enough for now. "
Jafari  said  he  didnât believe that the U.S. and Iran would go to war anytime soon  though some may question  his  reasoning.
Referring to the United States   he  said: "They know that if they begin a war between Iran and the United States  they will definitely be the main losers and their victory will by no means be guaranteed. Therefore  they won't start a war."

A:
Mohammad Ali Jafari
