Canada will impose retaliatory tariffs against the United States in response to the Trump administration's decision to extend steel and aluminum tariffs to Canada. During a press conference Thursday afternoon, Canadian Prime Minister Justin Trudeau called the American decision "totally unacceptable," adding he finds it "inconceivable" that "Canada could be considered a national security threat to the United States."

The details: Canada will impose its own tariffs against American steel, aluminum, and other products in the amount of $16.6 billion at rates of 25% and 10%, which represents the total value of Canada's 2017 steel and aluminum exports to the U.S. They'll go into effect on July 1, remaining until the U.S. ends its own tariffs.

Joe Biden leads President Trump 48% to 42% in Wisconsin and 49% to 43% in Pennsylvania, according to the latest CBS/YouGov Battleground Tracker poll.

Why it matters: Trump's surprise wins in the two states, where many voters broke his way after deciding the week before the election, helped propel him to an Electoral College victory over Hillary Clinton. Trump won Wisconsin with 47% of the vote and Pennsylvania with 48% in 2016, according to the New York Times.

Blumenthal calls classified briefing on Russian interference "absolutely chilling"

Sen. Richard Blumenthal (D- Conn.) called on the Trump administration to declassify intelligence detailing Russian efforts to influence the 2020 elections, telling MSNBC on Sunday that the classified briefing lawmakers received about the Kremlin's activities last week was "absolutely chilling."

The big picture: National Counterintelligence and Security Center Director William Evanina said in a statement Friday that the Russian government is "using a range of measures" to "denigrate" Joe Biden ahead of the election. China and Iran would prefer that Trump is defeated, according to Evanina.
