Former Treasury Secretary Jacob Lew said Democrats won’t be able to derail the Trump tax cut in the short-term and understands that they may take out their frustration by putting forward their own budget-busting priorities like guaranteed employment or single-payer health care.

In an interview with MarketWatch, Lew said the Republican decision to ram through the tax cut has poisoned the well, and cooperation between the parties to maintain the country’s fiscal heath may be lost for a long time.
