(WASHINGTON) -- Although some are questioning the timing of his new book, former Defense Secretary Robert Gates told CBS Sunday Morning that it wouldn't have made sense for him to wait until President Obama left office in 2017 to publish Duty: Memoirs of a Secretary of War.
Some of the juiciest parts of the Gates book have already been leaked before its publication this week, including his criticism of Obama and Vice President Joe Biden.
Gates says he stands by what he wrote, including allegations that the president began doubting the 2010 troop surge he ordered for Afghanistan.
Meanwhile, some fellow Republicans are stating publicly that perhaps Gates should have held off releasing his memoir.
Although Arizona Sen. John McCain told CNN's State of the Union that the former defense chief has the right "to voice his views any time he wants to," if McCain had had his ear, he would have advised Gates to delay the book.
On CBS' Face the Nation, Florida Sen. Marco Rubio was more blunt, saying, "My preference would be that people would refrain from writing these sorts of things until the president is out of office because I think it undermines the ability to conduct foreign policy."
