Los Angeles Mayor Antonia Villaraigosa was sworn in today as the new president of the US Conference of Mayors. The mayor used the platform to criticize Congress, calling for the expedited withdrawal of US troops from Afghanistan and a greater investment in domestic spending. On MSNBC's Morning Joe he said, "There needs to be an acknowledgement in the Beltway bubble that cities are suffering right now…that we need to make investments in infrastructure, in transportation."
