The corporate tax changes weren't his idea - they have been kicking around Capitol Hill with more or less bipartisan support for years, and it almost happened while Obama was president. The full package of changes wound up being highly politicized and controversial, but the corporate changes were always seen as very likely to pass sooner or later.

In fact it was Ben Carson who proposed cutting the tax rates the most (corporate tax rate -> 14.9%).
To claim this tax cut is a result of bipartisan legislation is rather odd.
