WASHINGTON (AP) — Vice President Joe Biden Monday launched a broadside at the slashing budget plan of House Republicans, kicking off a campaign to try to raise the profile of GOP budget cuts and income inequality as an election-year issue.

Biden attacked the budget plan by Rep. Paul Ryan — his GOP counterpart on the 2012 vice presidential ballot — as being tilted in favor of the wealthy and shortchanging investments in infrastructure, education and health research. He said it reflects “an orthodoxy that devalued … paychecks. They tilted the tax code in favor of unearned income, over-earned income, inherited wealth over take-home pay.”
