Trump should simply wait until Congress is on vacation and then handle these as recess appointments.

“Trump should simply wait until Congress is on vacation and then handle these as recess appointments.”

Yes.

After having put up qualified candidates in good faith.

They've been keeping Congress in 'pro forma' session to prevent Trump from making recess appointments. I would expect this to continue.

In the Federal government of the United States, either house of the Congress (the House of Representatives or the Senate) can hold a pro forma session at which no formal business is expected to be conducted.[6] This is usually to fulfill the obligation under the Constitution "that neither chamber can adjourn for more than three days without the consent of the other."[7] Pro forma sessions can also be used to prevent the President pocket-vetoing bills, or calling the Congress into special session.[8] They have also been used to prevent presidents from making recess appointments.
