Indefinite Detention and the National Defense Authorization Act

Why aren't our Senators standing up [to] the President when he writes stuff like this:

The Administration objects to and has serious legal and policy concerns about many of the detainee provisions in the bill. In their current form, some of these provisions disrupt the Executive branch's ability to enforce the law and impose unwise and unwarranted restrictions on the U.S. Government's ability to aggressively combat international terrorism; other provisions inject legal uncertainty and ambiguity that may only complicate the military's operations and detention practices.
Section 1031 attempts to expressly codify the detention authority that exists under the Authorization for Use of Military Force (Public Law 107-40) (the “AUMF”). The authorities granted by the AUMF, including the detention authority, are essential to our ability to protect the American people from the threat posed by al-Qa'ida and its associated forces, and have enabled us to confront the full range of threats this country faces from those organizations and individuals. Because the authorities codified in this section already exist, the Administration does not believe codification is necessary and poses some risk. After a decade of settled jurisprudence on detention authority, Congress must be careful not to open a whole new series of legal questions that will distract from our efforts to protect the country. While the current language minimizes many of those risks, future legislative action must ensure that the codification in statute of express military detention authority does not carry unintended consequences that could compromise our ability to protect the American people.

Repeal the 17th Amendment and our Senators will once again stand up for decentralized power, and they will enforce limits on the president and the rest of the federal government.
