Today is the birthday of the First Lady. What a year she has in store. Progressed Mercury is at 4 degrees, same number as her Mercury in Capricorn. Of course her Mercury in Capricorn is besieged by transiting Pluto and transiting Saturn. I think we can all agree she is under enormous pressure, which the transits show could affect her whole nervous system.
Saturn is her ruling planet with Sun in Capricorn, and right now it is also trining her Mars in Aquarius. Since Saturn co-rules Aquarius, this is a very beneficial, strengthening aspect.
