The first Congress Obama had to deal with (both being Dem run at the time) did not use it until the end of his second year in office.
Nevertheless, Obama made no recess appointments in his first year. In his second he did 28.
List of appointments on page 9 of the doc.
I don't know if the reason for no recess appointments in the first year was because they just all got approved or what.
Mitch McConnell put the Senate in recess while Obama was in office to allow Obama to make appointments.
For Trump, from his own party, he refused. Now Thune is doing the same thing.
So Obama got to select his own people whereas the GOP-e “leadership” is blocking Trump from being allowed to select people he wants to assist him
Gotta hand it to the GOP-e, they know how to be as worthless as teats on a boar.
