The Trump administration’s campaign to block AT&T’s megamerger with Time Warner is still going strong. The Justice Department announced Thursday it was appealing a federal judge’s ruling blessing the $81 billion deal. The government argues the merger would hurt competition, limit consumer choices, and raise the cost of streaming TV and movies. AT&T became the biggest pay-TV provider in the United States with its acquisition of DirecTV in 2014. It claims about 25 million of the 90 million or so U.S. households that are pay-TV customers. Time Warner owns CNN, HBO, the Warner Bros.

Canadian tariffs on many U.S. imports take effect this week to the tune of $12.5 billion. The newly taxed products include steel and iron, as well many smaller categories like detergent, ketchup, and pizza. U.S. President Donald Trump on Sunday threatened to fire the next shot in the mounting trade war. He wants to wait until after November’s midterm elections before agreeing to a new NAFTA trade agreement with Canada and Mexico. Sen. Pat Toomey, R-Pa., said the tariffs were bad news for the people of his state: “With Canada, we have a trade surplus. We have a surplus even in steel.

Amazon announced a deal Thursday to acquire PillPack, an online pharmacy that caters to people who take multiple prescription medications each day. It delivers prescription drugs in pre-sorted dose packaging and simplifies refills and renewals. Amazon will reportedly pay about $1 billion for the company. If regulators sign off on the deal, Amazon will have a path to disrupt the pharmaceutical industry the same way it’s shaken up just about everything else in retail. News of the deal rattled Wall Street on Thursday. Stocks of major drugstore chains like Walgreens and CVS dropped sharply.

Starbucks executive chairman Howard Schultz said Monday he would step down, further fueling speculation he will run for president.

Starbucks will close its more than 8,000 U.S. locations Tuesday afternoon for diversity training. The unusual move is designed to help restore the coffee chain’s image after employees at a Philadelphia location called police on two African-American men who sat down without ordering anything. The men said they were waiting for a business contact. All 175,000 Starbucks employees will take the “unconscious bias training,” a curriculum that focuses on prejudice people might not realize they have.

European companies are evaluating their options after U.S. President Donald Trump’s decision Tuesday to pull the United States out of the Iran nuclear accord. German multinational conglomorate Siemens and French airline manufacturer Airbus both said they would abide by reinstated U.S. sanctions against Iran but are waiting for more guidance on the specifics. U.S. Treasury Secretary Steven Mnuchin said he will revoke licenses held by Airbus and U.S.-based Boeing to sell jetliners to Iran but would negotiate certain exemptions. Beyond Boeing, the sanctions won’t have much effect on U.S.

T-Mobile and Sprint have agreed to merge in an all-stock transaction after weeks of talks between the two cellphone carriers. When the markets closed Friday, T-Mobile was worth $55 billion and Sprint was worth $26 billion. T-Mobile said the new company will retain the T-Mobile name and headquarters in Bellevue, Wash. It will also spend nearly $40 billion over three years building a nationwide 5G network. The merger would make T-Mobile the nation’s third-largest mobile carrier behind Verizon and AT&T. Federal regulators must still approve the move.
