Senate Minority Leader Chuck Schumer told his Twitter followers Tuesday to prepare for tax politics at the Thanksgiving dinner table, and then he took a shot at Treasury Secretary Steven Mnuchin.

The New York Democrat instructed his followers to bring a chart from a left-leaning think tank on the Republican tax plan to their holiday dinner in case a relative "tells you the Republican tax bill helps the middle class."

The chart, from the nonpartisan Center on Budget and Policy Priorities, shows that the Senate version of the tax reform bill would raise taxes on middle-class families if it were in place for 10 years.

Schumer followed that tweet with one of a photo of Secretary Steven Mnuchin and his wife, Louise Linton, posing awkwardly with a newly printed sheet of $1 bills bearing his signature.

The chart, which is based on estimates from Congress' nonpartisan Joint Committee on Taxation, partly reflects that the individual tax breaks would phase out over time in the Senate tax bill, a legislative workaround Republicans used to lower the revenue losses of the tax cuts on paper.

GOP leaders have said that they intend for the tax cuts to be made permanent in future years. "That’s not our policy," Trump budget director Mick Mulvaney said of the temporary cuts Tuesday morning in a Fox Business interview. "That’s simply the way to try to shoehorn the bill into these arcane rules in the Senate."

As for the unflattering photo of Mnuchin, the treasury secretary brushed off the commentary about it Sunday. “I guess that I should take that as a compliment, that I look like a villain in a great, successful James Bond movie," he said on "Fox News Sunday."
