PHILADELPHIA (AP) -- Vice presidential nominee Joe Biden is promoting the Democrats' economic plan as he visits southeastern Pennsylvania.
Speaking Friday at a union hall in Philadelphia, Biden says that presidential candidate Barack Obama's economic plan would cut taxes for all but the wealthiest Americans.
Biden criticized his Republican opponent, John McCain, for proposing a tax on health benefits provided by employers.
On the subject of free trade, Biden says countries should be forced to comply with labor and environmental regulations in order to become favored trading partners.
Biden, a senator from Delaware, is scheduled to visit a middle school in the Philadelphia suburb of Langhorne later Friday.
