question:
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.

question:
A solar system including five Earth-sized planets has been discovered which is so ancient it was born not long after the dawn of time - and experts say it could help find life on planets far older than we expected. The system's parent star, named Kepler-444, is 117 light years from Earth and 11.2 billion years old. When the sun-like star was formed out of a primordial cloud of gas and dust, the universe was just a fifth of its current age. Astronomers made the discovery after trawling through four years' worth of data collected by Nasa's Kepler space telescope.Solar system's parent star, named Kepler-444, is 117 light years from Earth11.2 billion-year-old star formed when the universe was a fifth of its ageFive Earth-sized planets orbit the star with years equivalent to 10 daysFind shows Earth-sized planets have formed throughout universe's history
