His retirement, which takes effect on July 31, gives Trump a second Supreme Court appointment in his 17 months in office after the Republican president past year selected Neil Gorsuch, who has already become one of the most conservative justices.
In the spring of 2016, before his election, Trump issued a list of 11 conservative judges he considered "representative of the kind of constitutional principles I value" and saying he would use it as "a guide to nominate our next United State Supreme Court justices".

There are only nine justices, who only get replaced if they retire or die, so who sits on it really matters.
