In the February 1999 Senate trial following the impeachment of Bill Clinton, Mc Cain voted to convict the president on both the perjury and obstruction of justice counts, saying Clinton had violated his sworn oath of office.In March 1999, Mc Cain voted to approve the NATO bombing campaign against the Federal Republic of Yugoslavia, saying that the ongoing genocide of the Kosovo War must be stopped and criticizing past Clinton administration inaction. The book traces Mc Cain's family background and childhood, covers his time at Annapolis and his service before and during the Vietnam War, concluding with his release from captivity in 1973.According to one reviewer, it describes "the kind of challenges that most of us can barely imagine.It's a fascinating history of a remarkable military family." Mc Cain announced his candidacy for president on September 27, 1999, in Nashua, New Hampshire, saying he was staging "a fight to take our government back from the power brokers and special interests, and return it to the people and the noble cause of freedom it was created to serve".Since January 1993, Mc Cain has been Chairman of the International Republican Institute, an organization partly funded by the U. Government that supports the emergence of political democracy worldwide. He would later explain that "under our Constitution, it is the president's call to make." Mc Cain attacked what he saw as the corrupting influence of large political contributions – from corporations, labor unions, other organizations, and wealthy individuals – and he made this his signature issue.
Stationed in the Gulf of Tonkin, Mc Cain and his fellow pilots became frustrated by micromanagement from Washington, and he would later write that "In all candor, we thought our civilian commanders were complete idiots who didn't have the least notion of what it took to win the war." On July 29, 1967, Mc Cain, by then a lieutenant commander, was near the epicenter of the USS Forrestal fire.
In 2015, Mc Cain became chairman of the Senate Armed Services Committee.
