5th District Congresswoman Elizabeth Esty is co-sponsoring legislation she says is aimed at strengthening and expanding Social Security.  The measure cuts taxes for Social Security recipients and provides a benefit bump for current and future beneficiaries.  Esty says this will ensure the system stays solvent through the next 75 years.  There are more than 600,000 retired workers, disabled people, and families who depend on Social Security to pay their bills in Connecticut.  Esty notes that includes 135,000 in the 5th district.
