Texas State Representative Leo Berman (R) furthered his campaign against President Obama Tuesday, a man that he has before characterized as "God's punishment on us," by introducing a bill that would require future presidential and vice-presidential candidates to produce "the original birth certificate indicating that the person is a natural-born United States citizen" to the Texas secretary of state.Berman told the Lubbock Avalanche-Journal that the bill, House Bill 295, is a compulsory step to take in order to correct an alleged gap in the law that allowed Barack Obama, who he believes could be foreign-born, to run for president."This bill is necessary because we have a president whom the American people don't know whether he was born in Kenya or some other place," Berman told the Avalanche-Journal.
