Senate Finance Committee Chairman Chuck Grassley blasted House Ways and Means Chairman Richard Neal for demanding that the IRS turn over President Donald Trump's tax returns.

Grassley, an Iowa Republican, asserted in a lengthy speech on Thursday that Neal, a Massachusetts Democrat, did not have a genuine legislative purpose for gathering the returns and said the reasoning outlined in his letter to Internal Revenue Service Commissioner Charles Rettig was about "finding a pretext to bring this president down."

"When you strip out all their pretexts, and when you strip out their circular logic, all you have are Democrats who want to go after the president any way they can," Grassley said. "They dislike him with a passion, and they want his tax returns to destroy him. That's all this is about, and it's Nixonian to the core."
