Trump claims ‘game over’ on Mueller as Dems say game on

Before the release of the Mueller report on Thursday, Donald Trump claimed the special counsel’s findings represented a “complete and total exoneration”. In fact, over the course of almost 450 pages, Robert Mueller describes 11 instances in which the president or his campaign engaged in potential obstruction of justice – and that’s just in the redacted version.

While Mueller’s team found no evidence of direct collusion between the Trump campaign and Russia, it makes clear that the Russian government interfered in the 2016 presidential election “in a sweeping and systematic fashion”, and that Trump’s campaign fully expected to benefit from those efforts. Such revelations would likely have ended any other American presidency.

Democrats dig in. Trump and his allies still claimed vindication, but Democrats demanded fresh hearings, sparking renewed talk of impeachment. Adam Schiff, the chair of the House intelligence committee, said the report was “not a vindication of Trump, but a condemnation”.

Sanders lies. The White House spokeswoman Sarah Sanders admitted to Mueller’s team that she had lied repeatedly in press briefings, when she claimed Trump’s firing of James Comey as FBI director was a result of the agency’s rank and file losing confidence in their director.

Trump’s lawyer. Democrats sharply criticised the attorney general, William Barr, for his decision not to prosecute the president for obstruction. “OUR Attorney General acts as Trump’s defense attorney,” tweeted 2020 hopeful Eric Swalwell, who demanded Barr resign.

Hundreds of thousands of Sudanese protesters have gathered outside the defense ministry in Khartoum, demanding the military hand over power to a civilian government after Omar al-Bashir was toppled and arrested last week after three decades in power. The transitional military council has agreed to meet some of the demonstrators’ demands, but said the transitional period could last up to two years before elections take place.

Economic crisis. The protests began more than three months ago, triggered by Sudan’s worsening economic crisis and culminating in the sit-in at military HQ, which started on 6 April.

Members of an armed, rightwing militia have been accused of “kidnapping” by the American Civil Liberties Union, after video clips emerged in which they appeared to detain a large group of migrants at the US-Mexico border in New Mexico and then co”ordinated with federal border patrol agents to have them arrested. The men belong to the self-styled United Constitutional Patriots, which is described by the ACLU as “an armed fascist militia organization”.

Blame Trump. In a letter to the state’s governor and attorney general, the ACLU of New Mexico said: “The Trump administration’s vile racism has emboldened white nationalists and fascists to flagrantly violate the law.”

Opinion

The Kavanaugh hearings only emphasised what has long been obvious: Republicans treat judges as partisan political appointees. Now Democrats must do the same, says Moira Donegan.

It is time for the Democrats to drop the pretense that the judiciary is apolitical, and admit that no progressive agenda can be enacted or maintained without a drastic overhaul of the federal judiciary. The next Democratic president must pack the courts.
