Trump says tax bill keeps getting better

President Donald Trump says the Republican tax bill "is getting better and better."

In an early morning Friday tweet, Trump wrote: "This is a once in a generation chance. Obstructionist Dems trying to block because they think it is too good and will not be given the credit!"

Republicans are eyeing a crucial final vote Friday on the $1.4 trillion Senate bill. GOP leaders have been making major changes up to the last minute, including one that would roll back some of the tax cuts after six years to appease deficit hawks.
