President Trump’s 25 percent tariffs against Canadian and Mexican goods are set to go into effect on Tuesday unless there is any last-minute negotiation today.

Why Trump is threatening tariffs on the neighbors: Trump wants to curb the flow of migrants and fentanyl into the United States. The tariffs were originally set to take effect on Feb. 1 but were punted by a month by Trump.

Hmm: Commerce Secretary Howard Lutnick told Fox News’s “Sunday Morning Features” that he sees the tariffs as a “fluid situation.”

Keep an eye on China, too: Trump is also planning to increase Chinese tariffs by an additional 10 percent.

President Trump and his top adviser, tech billionaire Elon Musk, have taken an axe to the federal government, purging many federal employees. Critics have argued that Trump’s selection for nixed roles has not been random. In fact, they argue the fired workers were very much chosen to stifle his political opponents.

Who has been nixed:

❌ People who provide oversight of Trump’s actions (like inspectors general and top FBI officials)

❌ Targeted retribution against agencies and institutions Trump has feuded with (like Democratic leaders of boards)

The Hill’s Rebecca Beitsch has looked into the mass firings and has divvied them up into several categories: oversight, Democratic boards, retaliatory firings and roughly 200,000 federal workers at large. It’s worth reading: ‘Inside Trump’s federal worker firings’

Crowds showed up near Sugarbush Resort in Vermont to protest Vice President Vance, who was visiting for a ski trip. The demonstrations were planned in advance, per AP, but were stronger after the Friday clash with Zelensky.
