Rick Perry, the former governor of Texas and 2012 Republican candidate for president, formally announced a second bid for the White House.
At a rally in Addison, Texas, this afternoon, Perry told a group of supporters: "Today I am announcing that I'm running for the presidency of the United States of America."
He decried that "weakness at home has led to weakness abroad" and that "Our economy is barely growing."
