• Donald Trump acknowledged that the sweeping tariffs he has imposed on Mexico, Canada and China may cause “some pain” for Americans, but said they were necessary to curb illegal immigration and the drug trade. “The USA has major deficits with Canada, Mexico, and China (and almost all countries!), owes 36 Trillion Dollars, and we’re not going to be the ‘Stupid Country’ any longer,” Trump said on Truth Social.

• Top Democrats slammed Donald Trump’s tariff plans, warning that they will hit working families and small businesses hard. Chuck Schumer, the Senate minority leader, led the charge by saying the president’s threatened tariffs would likely “hit Americans in their wallets”. “It would be nice if Donald Trump could start focusing on getting the prices down instead of making them go up.”

• Canada said it will take legal action under the relevant international bodies to challenge the 25% tariffs, a day after prime minster Justin Trudeau announced a wide array of concrete measures including a tit-for-tat 25% tariff phased in across C$155bn ($107bn) worth of US products.

• Mexico’s president Claudia Sheinbaum also ordered retaliatory tariffs in response to the US announcement. Sheinbaum said her government sought dialogue rather than confrontation with the US, but that Mexico had been forced to respond in kind. Mexico has been preparing possible retaliatory tariffs on US imports, ranging from 5% to 20%, on pork, cheese, fresh produce, manufactured steel and aluminum, according to reports.

• China said it would challenge Trump’s 10% tariffs at the World Trade Organization and take unspecified countermeasures. China’s commerce ministry said the imposition of tariffs by the US “seriously violates” WTO rules, urging the US to “engage in frank dialogue and strengthen cooperation”.

• Elon Musk’s “department of government efficiency” (Doge) has been given access to the federal payment system, exposing the sensitive personal data of millions of Americans as well as details of public contractors who compete directly with Musk’s own businesses, Ron Wyden, a Democratic senator from Oregon, said.

• Secretary of state Marco Rubio told Panama’s president, José Raúl Mulino, that Trump has determined that China’s influence threatens the Panama Canal and that immediate changes were needed or the Trump administration would take “measures necessary” to do so. Mulino, in response, said Panama’s sovereignty is “not in question”.

• The Trump administration has revoked temporary protected status (TPS) for more than 300,000 Venezuelans in the US, the New York Times reports. The federal TPS program allows for people to temporarily stay in the US if they cannot return safely to their home country. The termination means that those under TPS from Venezuela who received the protections in 2023 will lose their temporary status 60 days after the government publishes the termination notice, according to the Times.

• Dozens more staff at the US Agency for International Development (USAid) were put on leave over the weekend, according to a report, bringing the total number of senior staff at the aid agency who have been put on leave over the past week close to 100. Meanwhile, two senior USAid security officials were also put on administrative leave after refusing to hand over classified documents to Musk’s “department of government efficiency” (Doge).

• The UK prime minister, Keir Starmer, said he wanted to see “strong trading relations” with the US. Britain’s home secretary, Yvette Cooper, warned that Trump’s tariff plans could have a “really damaging impact” on the global economy and growth.

Meta’s chief executive, the tech billionaire Mark Zuckerberg, has grown increasingly close to Donald Trump since he won the 2024 election, including visiting him at Mar-a-Lago and celebrating with him at his inauguration.

Meanwhile, media personalities associated with some high-profile criticism of Trump or his Republican allies have started to leave the scene, including NBC’s former Meet the Press host Chuck Todd and CNN’s Jim Acosta, who was one of the most famous Trump-critical journalists on American television but who left his network after his show was shunted to a midnight slot.

“He’s dictating the news on his terms,” said Michael LaRosa, spokesperson for the former first lady Jill Biden. “He’s become America’s assignment editor.”

Other examples that have roiled American media are racking up. The Washington Post, owned by Amazon billionaire Jeff Bezos, endorsed Trump’s pick for attorney general, election denier Pam Bondi, calling her “qualified” and “serious”. Before the election, it killed an endorsement of Kamala Harris. At the same time, Amazon recently paid the first lady, Melania Trump, a staggering $40m for the rights to a documentary about her life.

Meanwhile, at the Los Angeles Times, the billionaire owner Patrick Soon-Shiong recently killed an editorial criticizing Trump’s cabinet picks and has granted significant editorial influence to Trump cheerleader Scott Jennings.

In a tumultuous first two weeks back in power in the White House, Donald Trump has targeted many familiar enemies, including one of his most passionate obsessions: the US media, whom he has frequently dubbed “enemies of the people”.

Trump’s new federal communications chair, Brendan Carr, is reported to have ordered an investigation into the sponsorship practices of taxpayer-supported NPR and PBS member stations – a media network long hated by conservatives who accuse it of a liberal slant.

At the same time, and just as concerning for some media watchers, core segments of the US media landscape – via the wealthy billionaires and gigantic corporations that own them – have seemingly caved under Trump’s pressure or apparently sought to curry favor with the new administration.

On Thursday, the New York Times reported that CBS News parent Paramount is in talks to settle a $10bn claim that it deceptively edited a 60 Minutes interview with Kamala Harris. Paramount is currently concluding an asset sale of its Hollywood studio business.

The news of Paramount’s decision – which has reportedly caused deep upset in the CBS newsroom – comes after ABC News agreed to pay $15m to Trump to settle a defamation lawsuit over inaccurate comments by anchor George Stephanopoulos that Trump had been found civilly liable for rape.

It also follows the move by social media giant Meta to pay $25m to settle a first amendment protections claim for “impermissible censorship” when it bounced Trump from Facebook and Instagram in 2021. About $22m of that fee will be a donation to Trump’s presidential library.

Claudia Sheinbaum, Mexico’s president, said her government will provide more details on the retaliatory tariffs she ordered on US goods on Monday.

Sheinbaum, in a statement on Sunday, she will announce details on her government’s “Plan B” as she insisted that Mexico “doesn’t want confrontation”.

“Problems are not addressed by imposing tariffs, but with talks and dialogue,” she said.

Canada’s department of finance has published a list of Americans products imported into Canada that it will target with a 25% retaliatory tariff starting Ton uesday.

The move comes in response to Donald Trump’s executive order on Saturday imposing a blanket 25% tariff on all Canadian goods imported into the US and 10% levies on Canadian energy.

The list shows products that will be hit in the first round of retaliatory tariffs by Canada starting Tuesday, and mounts to 30bn Canadian dollars’ worth of goods (about $20bn).

The impacted products include tobacco, produce, household appliances, firearms and military gear.

Canada is also preparing for a second, broader round of retaliatory tariffs in 21 days that will target another $86bn worth of US imports.

The US secretary of state, Marco Rubio told Panama’s president, José Raúl Mulino, in talks on Sunday that Donald Trump has determined that China’s influence threatens the Panama canal and that immediate changes were needed or the Trump administration would take “measures necessary” to do so.

The state department, in a summary of the meeting, said Rubio had informed Mulino that Trump believed the current situation at the canal was “unacceptable and that absent immediate changes, it would require the United States to take measures necessary to protect its rights” under a US treaty with Panama.
