The President’s tariffs are a tax on American consumers. They will raise the cost of everyday goods, including food, cars, electronics, and more. Watch my weekly update below.

Make no mistake, the American people will pay the price for the President’s trade war. Read my full statement below.

“Make no mistake: The American people will pay the price for the President’s trade war. The tariffs the President announced today will raise prices on groceries and electronics, cars and homes, and just about every other good on which we rely.

“Our economy is the envy of the world. In a sweeping move, President Trump is undoing our progress. Thanks to President Trump’s trade war, people will lose their jobs, seniors’ retirement savings will go down, medical costs will go up, and families will struggle to afford basic goods.

“Yet the President has gone on the record to make his stance clear, stating he ‘couldn’t care less’ if his tariffs raise prices on American families. It’s time Congressional Republicans join Democrats to stand up against the President’s attempt to tank our economy.”

Congressional Republicans are trying to change the way we estimate the cost of bills so they can pretend their tax cuts for the ultra-rich cost nothing. In reality, their cuts will add over $4 trillion to our national debt. Read more from my colleague @neal.house.gov.

Opinion | America can’t afford Trump’s tax cuts. So the GOP is playing pretend.

Extending the 2017 tax law could have long-lasting consequences to our fiscal health.
