The Republican National Committee is going all-out to try to discredit former FBI Director James Comey, whose new book, A Higher Loyalty, is already making waves. An ABC News/Washington Post poll released Friday finds President Trump and his allies have their work cut out for them. By a 48 percent to 32 percent margin, Americans say Comey is more believable than Trump, and by a similar 47-33 percent margin, they disapprove of Trump's decision to fire Comey — even though Americans don't view Comey all that favorably (30 percent see him favorably, 32 percent unfavorably).

Americans are much less ambivalent about Special Counsel Robert Mueller's investigation into Russian election meddling and possible Trump campaign collusion. A hefty 69 percent of Americans support the Russia collusion part of the investigation, but 64 percent also back Mueller looking into Trump's business activities — Trump's unilateral "red line" — and 58 percent favor him investigating Trump's alleged hush money payments. Women were 5, 8, and 15 points more likely than men to support those aspects of the investigation, respectively.

ABC News' George Stephanopoulos interviewed Comey, and he offered a preview on Friday's Good Morning America. The excerpt underscored the stakes of the believability question for Trump. "I honestly never thought these words would come out of my mouth," Comey told Stephanopoulos, "but I don't know whether the current president of the United States was with prostitutes peeing on each other in Moscow in 2013. It's possible, but I don't know."

The poll was conducted by Langer Research Associates between April 8-11 among a random sampling of 1,002 adults, and the results have a margin of sampling error of 3.5 percentage points. You can find more results at ABC News. Peter Weber

The White House revealed on Friday that President Trump spoke with Libya's Gen. Khalifa Haftar via phone call on Monday.

Trump reportedly praised Haftar, who is leading a rebel assault on the country's capital Tripoli, as he and his Libyan National Army try 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. "The call has no meaning, but we will respond to it," a protester told Reuters.

It is unclear why the White House waited several days to announce the phone call. Tim O'Donnell

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 amid a riot in Derry on Thursday as she was watching Irish nationalist youths clash with police during a riot. Police reportedly said McKee was not the gunman's intended target, but was hit by a bullet fired in the direction of the police officers.

Police described the shooting as a "terrorist incident." The Irish News reports that they 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.

There are fears that militant groups are trying to exploit political tensions caused by the United Kingdom's decision to leave the European Union, Reuters reports.

Northern Ireland's political leaders — nationalists and unionists alike — urged for calm following the violence.

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.

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."

Count Fox News host Chris Wallace among those who think Attorney General William Barr is going too far in playing defense for President Trump in the face of Special Counsel Robert Mueller's findings.

Wallace said on Friday that Barr's press conference about Mueller's report on seemed "to go against the grain of what Robert Mueller was suggesting in his own report," especially on the topic of obstruction of justice. While Mueller's report said the investigation had not definitively ruled on whether Trump obstructed justice in his effort to influence and shut down the probe into Russian election interference, Barr characterized the conclusions as too vague to merit further scrutiny.

Barr's insistence that Trump deserves to be let off the hook "seems even more troubling, and perhaps even more politically charged when you read the report," said Wallace.

"The reason that Robert Mueller didn't make a finding on obstruction wasn't because he didn't feel capable of doing it, but because he thought in direct contradiction to what Bill Barr said yesterday," that further action should be left to Congress, Wallace continued.

Despite House Majority Leader Steny Hoyer (D-Md.) trying to shut the door on impeachment this week, some Democrats are still trying to keep it open.

Rep. Steve Cohen (D-Tenn.) is the latest Congressional Democrat to advocate for the impeachment of President Trump, appearing on MSNBC on Friday and making it clear he disagrees with Hoyer and House Speaker Nancy Pelosi (D-Calif.).

"I believe impeachable offenses have been committed," Cohen told MSNBC's Hallie Jackson. "And I believe it's worthwhile to put in history's files what this man has done, and impeach him. But I don't think it's going to happen politically."

Cohen also expressed little faith that the Department of Justice will comply with Democrats' subpoena for the full Mueller report: "[I'm about] as confident as I am that the sun's gonna stop shining."

He also suggested considering a censure, which he said would at least put a "historical note" to Trump's conduct.

Cohen's Democratic colleague Rep. Elijah Cummings (D-Md.), the chairman of the House Oversight and Reform Committee, echoed his concerns over the report on MSNBC, "begging" voters to pay attention to Mueller's findings.

"I often say that people are going to look back at this time 200 years from now and ask the question, 'What did you do to reverse this?'" Cummings said.

This year's flu season is shaping up to be record-breaking in duration, despite a sharp decrease in the number of flu-related deaths from last year, reports The Associated Press.

A surprise second wave has drawn this year's season out to 21 weeks and counting, making it the longest in a decade and one of the longest seasons since the government started tracking seasons 20 years ago.

Despite the longer season, the number of deaths has significantly dipped from last year. An estimated 35,000-50,000 Americans have died from issues related to the disease in 2018-19, compared to 80,000 in 2017-18, per AP. Last year's season lasted 19 weeks and was the deadliest in 40 years.

Although an unpredictable virus, representative for the Centers for Disease Control and Prevention Lynnette Brammer says this year's flu season should be nearing its end, per AP. Marianne Dodson
