After a battle with the malignant brain tumor, glioblastoma, Senator John S, McCain, war hero and presidential candidate died early Sunday at the age of 81. One of the most distinguished American politicians of our time, he won bipartisan respect for his contributions to the shaping of US military strategy. He ran for the presidency against Barack Obama in 2008 and, when he lost, was returned to the senate by the state of Arizona. John McCain was also a good friend to Israel. The son and grandson of four-star admirals, he was renowned for his heroism as a prisoner of war in Vietnam. McCain was also one of the few powerful Republicans to consistently push back against President Donald Trump as presidential candidate and against his policies and conduct in the White House.
