According to Wikipedia:
Eric Holder, Jr. served as the 82nd Attorney General of the United States, from 2009 to 2015. Holder is the first African-American to hold the position of U.S. Attorney General. He previously served as a judge of the Superior Court of the District of Columbia and as United States Attorney for the District of Columbia (Source: Wikipedia)
Considering the money that must have been spent by MTN (We know that Eric Holder’s fee will be on the high side), It will be a huge blow if they eventually lose this case.
We would have to wait until the 18th of March to find out if this move will help MTN.
