GOP Stalwart Says He'll Back Hillary Brent Scowcroft was national security adviser for Ford, George HW, served 3 other GOP presidents By Jenn Gidman, Newser Staff Posted Jun 23, 2016 9:46 AM CDT 171 comments Comments In this Jan. 21, 2015, file photo, former National Security Adviser Brent Scowcroft testifies on Capitol Hill in Washington. (AP Photo/Cliff Owen, File) (Newser) – When you hear the name "Brent Scowcroft," certain things may come to mind, including "retired lieutenant general" and "heavyweight foreign policy adviser" to several GOP presidents, CNN notes. He served as national security adviser to Presidents Ford and George HW Bush, as well as in White House roles during the Nixon, Reagan, and Dubya years. But we can now also add "Hillary Clinton supporter" to his résumé: Just hours after Donald Trump ripped into Clinton during a speech in New York (see the AP's fact-check of it here), the 91-year-old Scowcroft offered his endorsement of the presumptive Democratic nominee, underscoring the trepidation that the GOP establishment has for Trump as its main shot at the White House. "The presidency requires the judgment and knowledge to make tough calls under pressure," Scowcroft said in a statement, per the Los Angeles Times. "[Clinton] has the wisdom and experience to lead our country at this critical time." What makes his venture into Dem territory not a 100% surprise: Scowcroft fell somewhat out of favor with the George W. Bush administration when he publicly expressed reservations about the war in Iraq. And as CNN notes, Scowcroft has had an impact on Democratic foreign policy. Even President Obama recently lauded Scowcroft, saying of the man who helped him put together his own security team, "I love that guy," per the Atlantic.
