The House has the ability to block recess appointments.
Actually, they don't.
Article 2 Section 3 of the Constitution of the United States.
He shall from time to time give to the Congress Information of the State of the Union, and recommend to their Consideration such Measures as he shall judge necessary and expedient; he 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; he shall receive Ambassadors and other public Ministers; he shall take Care that the Laws be faithfully executed, and shall Commission all the Officers of the United States.
Look at that, of the Senate wants to adjourn, and the House doesn't, the president has the power to adjourn Congress, totally eliminating the imaginary power you just gave to the House.
Want to tell me again how I don't understand the Constitution? Maybe you should spend more time reading it than complaining about how other people don't now what they are talking about.
