MITCHELL, S.D.(WNAX)- The three and a half trillion-dollar infrastructure and stimulus bill moving through Congress includes some major tax changes.

South Dakota Senator Mike Rounds says some of those could be business killers.

Rounds says there are proposed changes to capital gains taxes.

Rounds says democrats are pushing the payback for the spending to future years.

Supporters of the bill suggest it would revert tax rates to those seen in the 1960s and 70s.
