Yes, picks. Today, he will announce his first for the vacant seat once held by Scalia.
Within the next four years, he is likely to get at least one more and perhaps three more. Kennedy is 80 and has expressed an interest in retirement. Ginsburg will be 84 in weeks and her health is horrible. Breyer is 78.
Those are the most likely, though Roberts has heart issues and is 62. Thomas is not a picture of health at all and will be 69 in June. Alito is 67.
If Trump is re-elected in 2020, he could quite conceivable replace all seven of those Justices before the end of a second term (that would put Roberts at 69, Alito at 74, Thomas at 76, Breyer at 85, Kennedy at 87, and Ginsburg at 91; assuming each would be replaced the last year of his second term).
Expect the Senate GOPe to do everything possible to prevent Trump's picks from actually being confirmed, if they are strict Constitutionalists.
America needs to understand that our troops are not 'disposable'. Each represents a family; Fathers, Mothers, Sons, Daughters, Cousins, Uncles, Aunts... Our Citizens are our most valuable treasure; we waste far too many.
