It does say, at one web site, that John McCain authored a “relocation” bill. The 1974 Navajo-Hopi Settlement Act promoted having the U.S. government finance the eviction of all the people living in an area of the Navajo Nation. Because the header for this portion of the web site reads, “1974 Relocation Act”, it appeared as if McCain had authored the legislation back in 1974. 
But this seems iffy. McCain was a prisoner of war in Vietnam until 1973. He retired from the U.S. Navy in 1981. He was elected to Congress in 1982, and in 1986 was elected to the Senate. 
The Daily Kos has an article from June 28, 2015, “McCain & The Forced Navajo Relocation Law”, which gives more detail on the subject. John McCain had retired from the Navy in 1981 and had entered politics. It was around then, not in 1974, that McCain kept “pulling the trigger with S1973-1 and S.1003.” 
S.1973 is listed at the congressional web site as a bill to improve management of the National Laboratories, enhance technology commercialization, facilitate public-private partnerships, and for other purposes. 
As for S.1003, cited by Winter Rabbit in his Daily Kos article, that is murky. The 113th Congress (2013-2014) had a “S.1003 – Comprehensive Student Loan Protection Act”.  The 114th Congress (2015-2016) has a “S.1003 – Trade Adjustment Assistance Enhancement Act of 2015”.  Winter Rabbit clarifies this by sourcing “S.1003” to a law amended many times, 25 U.S.C. 640d-11. John McCain had introduced key amendments. These and other amendments were introduced by Senator McCain as public law in 1996 through 1999, and some were submitted to the Senate and House in 2005 as PL S.1003, subsequently incorporated into the language of the 2005 amendment of 25 U.S.C. 40d-11. Among the alleged “sponsors” of Senator McCain were Peabody Coal and Bechtel. 
So it appears at this point that Senator John McCain is at least connected with a bill which included having the U.S. government finance the eviction of all the people living in part of Navajo Nation.  The U.S. government was to pay for the evictions. That means the U.S. taxpayer was to pay. That was mighty lucky for Peabody Coal to have you and I pay for the “relocation” while Peabody Coal gets to keep the coal profit.
U.S. Senators Tom Udall and John McCain have requested a hearing on the Gold King Mine spill of August 5, 2015, which dumped waste from a mine into the Animas River. “Through our ongoing conversations with leaders of the Navajo Nation, we understand their dissatisfaction with the EPA’s response to the spill, and share their concerns that toxic substances might flow onto their lands and waters,” Udall and McCain said in a joint statement.  I cannot find at this point exactly when the Udall-McCain hearing is to take place.
The Department of the Interior is conducting its own investigation into the massive spill of toxic metals into the Animas river. 
McCain Offers Shiny Glass Beads
Was Manhattan Island purchased from Indians for $24 worth of beads? This appears to be a myth. “Only one period document mentions anything about the purchase of Manhattan. This letter states that the island was purchased from the Indians for 60 guilders worth of trade goods… No reason beads couldn’t have been included, but nothing tells us exactly what the mix was. Indians were notoriously shrewd traders and would not have been fooled by worthless trinkets.” 
At least some of the “notoriously shrewd traders” of Navajo Nation weren’t buying when, consequent to the Gold King Mine spill, John McCain paid a visit and offered them shiny glass beads in the form of a Navajo Code Talkers Museum. At the moment anyway the Navajo are more interested in getting clean water than in getting a museum. A contractor for the Environmental Protection Agency (EPA) brought nine “dirty oilfield” tanks filled with water intended for crops and livestock, according to a report by KOB Eyewitness News 4. “The EPA told us that these tanks hold only clean water for drinking,” said Navajo Nation President Russell Begaye. “Clearly it is just a lie. Clearly, it is an oil tank. That’s what it is.” 
The water situation at Navajo Nation now is critical. They need immediate relief and are calling for help from anyone with water-hauling capabilities. 
So could we perhaps just get these people some clean water? Is that too much to ask? Senator John McCain is in the spotlight. How will he respond, in real time, to this emergency? Maybe the beknighted Senator could hold a press conference and issue an urgent appeal for water.
