The year before Trump took office, the US averaged +168,000 jobs per month.

It added just 119,000 jobs TOTAL in 7 months since Trump's tariffs began.

The unemployment rate just hit its highest level in 4+ years.

Even Trump's Chief of Staff admits his tariffs hurt our economy.

According to a new court filing, the Trump administration has a six-page list of banned words that Head Start locations are forbidden from using when describing their programs.
Among the censored words: "disability," "race," "women," "trauma," "Gulf of Mexico." Short thread with the full list. 🧵

Excellent piece from @stanveuger.bsky.social and Clark Packard on why Congress must reclaim their clear authority over the power of the purse.

See Article 1 Section 8 of the US constitution.

The image that always sticks in my mind for that total breakdown of the Constitution isn't Jan 6 itself, it's Pelosi literally rallying troops in front of the Capitol to protect Congress from the president.

Kimberly Clausing @kclausing.bsky.social · Nov 5

A good day to re-up this thread on why tariffs are a poor tax policy instrument.

Also relevant today, this broad use of tariffs definitely exceeds the President's authority under IEEPA.

Early indications suggest the court agrees.

My new column with Maurice Obstfeld in VoxEU argues that the broad tariffs of the Trump administration are not well suited to tax policy, macroeconomic, or other aims.

cepr.org/voxeu/column...

Trump’s tariffs as fiscal folly

In 2025, the US government underwent a large fiscal switch, with Congress enacting large income tax cuts and the second Trump administration putting new tariffs on goods at levels not seen in the US since the Great Depression. This column evaluates tariffs as a broad tool of fiscal policy, reviewing both tax policy and macroeconomic considerations, and concludes that this fiscal switch will leave most Americans worse off.

Ok so the Trump administration blew up the international agreement to tax CO2 from shipping. 14 years ago the Obama administration successfully opposed applying the EU carbon price to US airlines operating in Europe.

Just because Ds and Rs both agree on something doesn't mean it's right.

. Tariffs as Fiscal Policy
Kimberly A. Clausing, Maurice Obstfeld #34192

Abstract:
The year 2025 brought a remarkable shift in the role of tariffs in the US economy, as the Trump administration simultaneously escalated the use of broad tariffs and ensured that Congress enacted large income tax cuts. This fiscal switch has important implications for the US tax system. While maintaining tariff rates at summer 2025 levels would generate large government revenues, such broad tariffs have significant downsides: Efficiency losses would approach one-third of revenues raised, the tax system would be less progressive, and there would be serious tax administration concerns. The fiscal shift also has significant macroeconomic implications, although probably not the intended ones. Broad tariffs generate a large negative supply shock, simultaneously raising prices and reducing macroeconomic activity.
