CHICAGO: A Muslim teenager arrested after a Texas teacher mistook his homemade clock for a bomb won invitations to the White House, Google, and Facebook Wednesday in a surge of public support. President Barack Obama congratulated Ahmed Mohamed, 14, on his skills in a pointed rebuke to school and police officials — who defended his arrest — amid accusations of Islamophobia. “Cool clock, Ahmed. Want to bring it to the White House? We should inspire more kids like you to like science. It’s what makes America great,” Obama tweeted. Mohamed told the Dallas Morning News he had hoped to impress teachers by bringing the clock to school on Monday.
