Story highlights Pelosi said President Donald Trump and Republicans are moving too fast on the plan

She called the tax plan "a gift to corporate America"

Washington (CNN) House Minority Leader Nancy Pelosi says the Republican tax plan isn't all that it seems, expressing her frustration over a lack of collaboration between the two parties.

Speaking with CNN's Jake Tapper on "State of the Union" Sunday morning, Pelosi said President Donald Trump and Republicans are moving too fast.
