Makes little sense as it’s on a FTA channel. Probably will come back during the inauguration and around big events like The State of the Union.
I agree in that it doesn't need to be simulcast live every week, but I should point out CNBC is only on on satellite and cable, so Freeview (terrestrial) viewers can only watch it when it's shown on Sky News.
So with that I agree that Sky News could make better use of their evening/overnight hours by repeating Meet the Press at a later time.
In fact I would argue there's merit for using their weekday overnight hours to air other (C)NBC programming, such as Nightly News which is also currently on CNBC, or/and The News with Shep Smith which we only see when CNBC has a gap in the schedule. For example Nightly News could easily fit in to the 12:30am slot they repeat the press preview in.
