As President Obama comes under fire for his national security policies — defined, most recently, by the discovery that his administration has been secretly collecting millions of Americans’ phone records and monitoring their online activity — one clarion voice has emerged as the commander-in-chief’s greatest champion and defender: Ari Fleischer. In recent weeks, the former George W. Bush press secretary has routinely used his perch as a Republican pundit to hail what he views as Obama’s continuation of his predecessor’s policies — a somewhat mischievous compliment that manages to praise his old boss and troll the political left at the same time. “For a future president, whoever takes the reins in 2017 will be able to look back over 16 years of Bush and Obama actions — Guantanamo, drone strikes, wiretaps, military commissions — that all served as the centerpieces of how to keep America safe in an age of terror,” Fleischer told BuzzFeed Thursday, as the Obama administration faced a barrage of attacks over the NSA’s snooping. Fleischer gave a similar quote to Politico, which made a headline out of his favorite trolling soundbite, “Bush’s 4th term.” He also took to Twitter to defend Obama, with a series of Tweets that drew angry, scornful responses from liberals.
