He has a right to.  Article II Sec. 3: [The President] may, on extraordinary Occasions, convene both Houses, or either of them, and in Case of Disagreement between them, with Respect to the Time of Adjournment, he may adjourn them to such Time as he shall think proper  https://www.heritage.org/constitution/articles/2/essays/96/convening-of-congress What this means is, if the House or Senate are "de facto" Adjourned for 3 or more days, Trump can force them to be NOT BE FACTO Adjourned, by either forcing them to declare Adjourned, or forcing them to come to washington, in SHACKLES and ARRESTED if need be, to force a quorum. Luckily a Quorum can be very few in "Executive Session" https://en.wikipedia.org/wiki/Standing_Rules_of_the_United_States_Senate Senate Consideration of Presidential Nominations: Committee and Floor Procedure:    https://fas.org/sgp/crs/misc/RL31980.pdf https://en.wikipedia.org/wiki/Executive_session Sometimes the Democrats give up and let a pile to expedite "Executive Session" : https://www.huffpost.com/entry/senate-democrats-trump-federal-judges_n_5b86c0eee4b0cf7b00313783 Obama ruled like a fucking roman emperor whenever congress (house and senate) were closed for 3 days or more. Obama's fascist "Obama Pen". But now TRUMP gets no similar courtesy for foot dragging emergency appointments.
