The Senate has a say in who is approved. Article 2, Section 2 of the Constitution lays out the basis of that.
“He shall have power, by and with the advice and consent of the senate, to make treaties, provided two-thirds of the senators present concur; and he shall nominate, and by and with the advice and consent of the senate, shall appoint ambassadors, other public ministers and consuls, judges of the supreme court, and all other officers of the United States, whose appointments are not herein otherwise provided for, and which shall be established by law. But the Congress may by law vest the appointment of such inferior officers, as they think proper, in the president alone, in the courts of law, or in the heads of departments.”You notice that the cabinet is not specifically mentioned but most agree it would be included.
The mysterious crisis that the left if finding has to do with the president firing a cabinet member, not appointing one. Historically this was dealt with in the impeachment of Andrew Johnson. One of his cabinet members was basically a seditious spy for Radical Republicans. He was making it impossible for Johnson to do his job, so he fired the man. Congress said, “You can’t do that” and started impeachment procedures. It failed by one vote in the Senate and thus you would assume that precedent says the president can fire.
This is the kind of nonsense that you can expect from a political party that finds the right to an abortion in the Constitution but can’t find the right to bear arms.
It is a moot point anyway. Sessions was not “fired” he was asked to resign, and he did.
The Democrats have not even finished contesting elections and already the push to make us a banana republic is moving forward.
