Sen. Elizabeth Warren (D-Mass.) on Friday called on the House to initiate impeachment proceedings against President Trump. Warren said her reasoning is based on the findings of Special Counsel Robert Mueller, which Attorney General William Barr made available — with redactions — to Congress and the public on Thursday. "The severity of this misconduct demands that elected officials in both parties set aside political considerations and do their constitutional duty," Warren tweeted. In an appearance on CNN's The Rachel Maddow Show on Friday evening, Warren added that "the report is absolutely clear that a foreign government attacked our electoral system to help Donald Trump." Warren is the first 2020 Democratic presidential candidate to openly call for impeachment.

House Judiciary Chair Jerrold Nadler (D-N.Y.) issued a subpoena on Friday to obtain the full, unredacted version of Special Counsel Robert Mueller's report on Russian election interference and the Trump campaign's conduct surrounding the meddling. The House Judiciary Committee approved the subpoena earlier this month, anticipating a desire for an unredacted report and Mueller's underlying documentation. The subpoena has now been fired off, demanding to see Mueller's evidence and summaries of key witness interviews by May 1. If Attorney General William Barr ignores it, the Judiciary Committee could hold him in contempt, setting up a potentially lengthy court battle. Nadler said the report was troubling and "it now falls to Congress to determine the full scope of that alleged misconduct."

Police arrested two men in connection with the murder of journalist Lyra McKee in Derry, Northern Ireland, on Saturday. McKee, 29, was shot and killed in Derry on Thursday as she was watching Irish nationalist youths clash with police during a riot. Police believe the suspects in the murder are linked to the dissident Republican group the New Irish Republican Army, an offshoot of the Irish Republican Army which remains opposed to the 1998 Good Friday Agreement and the fragile ceasefire in Northern Ireland. McKee's murder follows the explosion of a large car bomb in Derry in January, which was also blamed on the New IRA. Northern Ireland's political leaders — nationalists and unionists alike — urged for calm following the violence.

The White House revealed on Friday that President Trump spoke with Libya's Gen. Khalifa Haftar via a phone call on Monday. Trump reportedly praised Haftar, who is leading a rebel assault on the country's capital Tripoli, as he tries to wrest control from the incumbent United Nations-backed government. The two discussed Haftar's "significant role" in fighting terrorism and securing Libya's oil resources, as well as their "shared vision" for Libya's future. Trump's praise of Haftar is seen as a reversal of United States policy in Libya — Secretary of State Michael Pompeo demanded a halt to Haftar's assault earlier this month. The news of the phone call reportedly led to thousands of Libyans taking to the streets in protest. It is unclear why the White House waited several days to announce the phone call.

The Washington Post reported on Friday that the United States made the first arrest related to the mysterious raid of North Korea's Embassy in Spain in February. During the raid, masked intruders tied up staff and stole computers before fleeing to the U.S. On Thursday, U.S. authorities arrested Christopher Ahn, a former U.S. Marine. Ahn is a member of Free Joseon, a group dedicated to the overthrow of North Korean leader Kim Jong Un and his familial dynasty. Free Joseon reportedly claimed responsibility for the embassy raid in March. The State Department said that the United States had nothing to do with the incident, despite initial reports out of Spain that the CIA was involved.
