WASHINGTON—The White House is moving swiftly to galvanize the outpouring of support for slain conservative activist Charlie Kirk into political momentum, as President Trump’s advisers weigh a slate of executive actions targeting liberal organizations. Among the actions being discussed by the president’s team: reviewing the tax-exempt status of left-leaning nonprofit groups, according to administration officials. The president could begin rolling out the actions as soon as this week, officials said, part of a bid to harness support for Kirk, particularly among young voters, ahead of the midterm elections.
