With President Donald Trump's sweeping agenda hitting the rocks as he edges toward the 100-day mark, top aides, political allies and donors are embroiled in a furious round of finger-pointing over who is at fault.

The recriminations extend far beyond the implosion of the GOP's Obamacare repeal on Friday. Senior aides are lashing each other over their inability to stem a never-ending tide of negative stories about the president. There is second-guessing of the Republican National Committee's efforts to mobilize Trump's electoral coalition on behalf of his legislative priorities. At the Environmental Protection Agency, a top official quit recently amid accusations the department is failing to advance the president's campaign promises. And one of Trump's most generous benefactors, Rebekah Mercer, has expressed frustration over the direction of the administration.

This account of White House infighting is based on interviews with more than two dozen Trump aides, confidants and others close to his administration, all of whom spoke on the condition of anonymity. They described a distracting and toxic atmosphere, with warring power centers blaming one another for an ever-growing list of setbacks. The dysfunction has further paralyzed an administration struggling to deliver on its blunt promises of wholesale change.
