After more than six months in office, and despite full Republican control of Congress, Trump cannot point to a single substantial legislative achievement. The bid to repeal the Affordable Care Act, better known as Obamacare, which finally went down in flames in the Senate last week, was the most spectacular and telling of Trump’s failures. His executive orders, such as the racist ban on Muslim travellers and last week’s bigoted attack on transgender people in the military, have mostly run foul of the courts or been pre-emptively ignored by those charged with implementing them.

Trump has instead squandered the political goodwill that traditionally accompanies a presidential honeymoon, shocked and outraged many middle-of-the-road voters who initially gave him the benefit of the doubt, thoroughly alienated Republican party traditionalists, who had tried in vain to swallow their doubts, and undermined the authority of the office of the president. Trump, a supposedly ace chief executive, has now lost a chief of staff, a deputy chief of staff, a national security adviser, a communications director and a press secretary in short order. To lose one or even two of his most senior people might be excused as unfortunate. To lose all five suggests the fault is his.

President Trump personally dictated a statement that was issued after revelations that Donald Trump Jr. met with a Russian lawyer during the 2016 election.

The White House has confirmed Donald Trump played a role in drafting a misleading statement about his son’s meeting with a Russian lawyer.

On Tuesday, the press secretary, Sarah Huckabee Sanders, contradicted Trump’s attorney, Jay Sekulow, who said the president had had no involvement.
