Wisconsin's Republican governor Scott Walker became the 20th major party candidate for president on Monday with a speech that name-checked Planned Parenthood, the ISIS terror army, Hillary Clinton, Vladimir Putin and the Kohl's chain of department stores. The early GOP favorite has waited month after month to enter the race as others leaped in, but finally declared his availability for the White House in a suburb of Milwaukee. Walker cast himself as the economic and military heir to Ronald Reagan, and a hardscrabble survivor with a statewide record that, he says, can scale up to the size of a nation.Walker joins the fray with 14 other Republicans and five DemocratsPitches Kohl's Department Stores as a volume-pricing example of how the US tax code should reach more workers with lower ratesSlams Obama for 'leading from behind,' being weak on Iran and Russia, and failing to be a friend to IsraelPledges to repeal Obamacare and green-light the Keystone XL pipelineCasual Walker wore no necktie and spoke with a lapel microphone – reciting a memorized speech without a teleprompter – and enters the race in 2nd place in polls 
 Question:'We defunded _ and enacted pro-life legislation,' he said.

(CNN) Fethullah Gulen, the reclusive cleric accused by Turkey of hatching a military coup attempt, concedes that his supporters could have been involved in the putsch but again denied any direct connection. "There might have been some sympathetic people [to Gulen] among them," he told CNN's Fareed Zakaria in an interview. President Recep Tayyip Erdogan has pointed the finger of blame for the failed uprising squarely at Gulen. A bitter rival of the embattled President, Gulen is the leader of a popular movement called Hizmet. But the government refers to his group as the "Fethullah Gulen Terrorist Organization." The 77-year-old imam, who left Turkey for the United States in 1999, has been living in self-imposed exile in Saylorsburg, Pennsylvania.President Recep Tayyip Erdogan has pointed the finger of blame for the failed uprising squarely at GulenGulen calls for international organization to investigate government claims connecting him to the coup attempt
