The State Department under President Obama used taxpayer money to fund the political activities of a group in Albania backed by liberal billionaire George Soros, a conservative watchdog group says.

THE LEAD STORY - FACEBOOK BREACH WORSE THAN THOUGHT: The personal information of up to 87 million users may have been "improperly shared" with political consulting firm Cambridge Analytica, Facebook said ... The social media giant's chief technology officer, Mike Schroepfer, revealed the number in a blog post Wednesday, and said the tens of millions affected were "mostly in the US." It was previously believed that around 50 million users were affected. Facebook's blog post also detailed the company's efforts to be more transparent about changes regarding security on the social media platform and its user data. CEO Mark Zuckerberg, who will testify next week on Capitol Hill , told reporters on Wednesday he made a "huge mistake" in failing to take a broad enough view of what Facebook's responsibility in the world is.

MARCHING ORDERS TO THE BORDER: President Trump signed a proclamation Wednesday night to send the National Guard to the U.S.-Mexico border immediately, a senior White House official told Fox News, in response to what the administration described as an "unacceptable" flow of drugs, criminal activity and illegal immigrants ... Governors of several states voiced support for Trump's decision. Homeland Security Secretary Kirstjen Nielsen said at the White House press briefing that the signing would be done in conjunction with governors and that the administration hoped the deployment would begin "immediately." "Despite a number of steps this administration has taken...we continue to see unacceptable levels of illegal drugs, dangerous gang activity transnational criminal organizations and illegal immigration flow across our border," she said.

NUNES WANTS STONEWALLING TO STOP: U.S. Rep. Devin Nunes, R-Calif., chairman of the House Intelligence Committee, has threatened to enforce a subpoena over the FBI memo that kick-started the Russia counterintelligience investigation ... Congressional investigators are still facing roadblocks over FBI records, despite promises of cooperation from FBI Director Christopher Wray and Deputy Attorney General Rod Rosenstein, according to a letter obtained by Fox News. Nunes, wrote that he has been denied a clean copy of the 2016 FBI memo that started the Russia probe. Fox News is told the FBI memo was likely drafted by, or with input from, Agent Peter Strzok in July 2016, when the bureau formally opened its counterintelligence investigation. Strzok was removed from the investigation last year by Special Counsel Robert Mueller after anti-Trump texts between Strzok and FBI lawyer Lisa Page were discovered. Nunes threatened enforcement of subpoenas that were issued last August if the FBI memo is not provided by April 11.

FOX NEWS EXCLUSIVE - EPA'S SCOTT PRUITT ON THE HOT SEAT: Embattled Environmental Protection Agency Administrator Scott Pruitt fired back at critics Wednesday, defending his decision to take a $50 a day condo rental from the wife of a lobbyist and claiming he just found out about a controversial pay raise for two of his staff members ... “My staff and I found out about it yesterday and I changed it,” Pruitt told Fox News in an exclusive wide-ranging interview. When pressed to provide specifics, Pruitt said he wasn’t sure who would be held accountable or if the person who authorized the raise was a career EPA employee or a political appointee.

FOLLOWING THE MONEY: The Obama administration sent U.S. taxpayer funds to a group backed by billionaire George Soros to fund left-wing activities in Albania, a conservative watchdog group Judicial Watch says ... The group obtained 32 pages of records from the Justice Department this week through a May 2017 Freedom of Information Act (FOIA) lawsuit against the State Department and U.S. Agency for International Development (USAID.) The new documents show USAID funds were sent through the agency’s Civil Society Project to back Soros’ left-wing "East West Management Institute" through USAID's "Justice for All" campaign. USAID provided $8.8 million in 2016 to that campaign. Judicial Watch said, though, that money was used specifically to give the Albanian socialist government greater control of the judiciary system.
