Yes. But remember it is very difficult to receive an authentic autograph from a sitting president. Most likely you will receive a pre-print or secretarial. But anything is possible with Trump since he is not the norm. I'm sure like previous Presidents, he will receive thousands of letters a day.

I wondering if this is not a secretarial since she has been in Europe since the end of June on tour. According to her website I believe her last show was on June 17 in Vienna and her next one is in Monte Carlo on August 2. Hopefully she came back to the States during the hiatus.
