The New York Times makes it easy to find out where our Senators stand:

The Senate has confirmed each of President Trump’s nominees that it has voted on so far. Fifteen members of the cabinet and eight other top administration posts require Senate confirmation.

All but three of the “no” votes have come from Democrats and have essentially been symbolic statements of opposition. Nominees need only a simple majority to be confirmed, and Republicans hold 52 seats in the Senate.
