The USA is celebrating its 250th national birthday this year...

Under the banner of Freedom 250, the USA is running all sorts of celebrations and initiatives. Under the banner of Rededicate 250, a program of national prayer, praise and thanksgiving, on Sunday May 17 the American people will come together at the National Mall to prepare for the 250th birthday with prayer, Scripture, thanksgiving and rededication of the country as One Nation Under God. You can see more about the program at the linked website. Rabbi Meir Soloveichik is listed among the faith leaders who will be participating in the program.

And to that end, President Trump, as posted on the White House website, has called on and encourages all Jewish Americans, with Jewish American Heritage Month being now (May is always Jewish American Heritage Month), to observe a "national Sabbath" - the Shabbos of May 15-16 from sundown  to nightfall, friends, families and communities should "come together in gratitude for our great nation", recognizing the sacre Jewish tradition of setting aside time for rest, reflection and gratitude to the Almighty. President Trump further calls " I call upon Americans to celebrate the heritage and contributions of Jewish Americans and to observe this month with appropriate programs, activities, and ceremonies.  I further call on all Americans to celebrate their faith and freedom throughout this year, during this month, and especially on Shabbat to celebrate our 250th year."

So, keep Shabbos for Trump on May 15... :-) .. He actually does not reference keep halachic shabbos, but rest, reflection and gratitude are great things as well....
