MADRID (Reuters) -After surviving the perilous trek through the jungle of Panama's Darien Gap with his wife and three daughters to reach the United States, Venezuelan policeman Alberto Peña thought he had found a haven from the persecution he says he fled from back home. But two years later, President Donald Trump's drive to end temporary protected status for hundreds of thousands of Venezuelans in the U.S. forced Peña and his family to move once again - this time to Spain. "Migrating twice is difficult, both for oneself and for one's children," Peña said from Madrid.
