The Constitution allows for Trump to pick his own SCOTUS judge should the Senate fail to confirm his pick.

According to The Constitution, it also gives the Chief Executive the opportunity to fill a vacancy on the Court temporarily, bypassing the Senate initially, if a nominee languishes in the Senate without final action.

According to Article II, when the Senate has gone into recess and the vacancy a president seeks to fill remains, such an appointment requires no action at all by the Senate, but the appointee can only serve until the end of the following Senate session.  The president (if still in office) can then try again during a new Senate session, by making a new nomination, and that must be reviewed by the Senate.

Imagine the fireworks if Trump makes a recess appointment.
