2. Today at the White House, President Trump and the Senate majority leader, Mitch McConnell, put aside their recent feud at an impromptu 45-minute news conference. The sudden détente highlighted how utterly crucial the White House’s tax plan is for Republicans now.

“The relationship is very good,” Mr. Trump told reporters. “We are fighting for the same thing. We are fighting for lower taxes, big tax cuts, the biggest tax cuts in the history of our nation.”

The president commented on a wide range of other subjects. Among the highlights: He blamed Cuba for the mysterious attacks on American diplomats at the embassy in Havana, and falsely claimed that President Obama never contacted families of fallen soldiers.
