He has undermined efforts by career diplomats to deliver messages to Washington about corruption and democratic backsliding in Hungary. And he has privately acted as a broker for Mr. Orban’s point of view, taking positions contrary to United States policy, according to interviews with roughly two dozen current and former American and foreign officials as well as others who have worked with Mr. Cornstein.
Mr. McCabe’s memo, one of several that he wrote, highlights the conflicting roles that Mr. Rosenstein plays in the case. He supervises the special counsel investigation and has told colleagues that protecting it is among his highest priorities. But many current and former law enforcement officials are suspicious of some of his other actions, including allowing some of Mr. Trump’s congressional allies to view crucial documents from the investigation.
Federal prosecutors in Manhattan obtained the search warrant after receiving a referral from the special counsel, Robert S. Mueller III, according to Mr. Cohen’s lawyer, who called the search “completely inappropriate and unnecessary.” The search does not appear to be directly related to Mr. Mueller’s investigation, but likely resulted from information he had uncovered and gave to prosecutors in New York.
Andrew G. McCabe, the former F.B.I. deputy director and a frequent target of President Trump’s scorn, was fired Friday after Attorney General Jeff Sessions rejected an appeal that would have let him retire this weekend.vMr. McCabe promptly declared that his firing, and Mr. Trump’s persistent needling, were intended to undermine the special counsel’s investigation in which he is a potential witness.
Attorney General Jeff Sessions is reviewing a recommendation to fire the former F.B.I. deputy director, Andrew G. McCabe, just days before he is scheduled to retire on Sunday, people briefed on the matter said. Mr. McCabe was a frequent target of attack from President Trump, who taunted him both publicly and privately.
A business associate of President Trump promised in 2015 to engineer a real estate deal with the aid of the president of Russia, Vladimir V. Putin, that he said would help Mr. Trump win the presidency. The business associate, Felix Sater, wrote a series of emails to Mr. Trump’s lawyer, Michael Cohen, in which he boasted about his ties to Mr. Putin and predicted that building a Trump Tower in Moscow would be a political boon to Mr. Trump’s candidacy.
Senior officials across the government became convinced in January that the incoming national security adviser, Michael T. Flynn, had become vulnerable to Russian blackmail. At the F.B.I., the C.I.A., the Justice Department and the Office of the Director of National Intelligence — agencies responsible for keeping American secrets safe from foreign spies — career officials agreed that Mr. Flynn represented an urgent problem. Yet nearly every day for three weeks, the new C.I.A. director, Mike Pompeo, sat in the Oval Office and briefed President Trump on the nation’s most sensitive intelligence — with Mr. Flynn listening.
John O. Brennan, the former director of the C.I.A., offered the fullest public account yet of how the federal investigation into Russian election meddling began. In testimony before the House Intelligence Committee, Mr. Brennan described a nerve-fraying few months as American authorities realized that the election was under attack and worried that Mr. Trump’s campaign might be aiding that fight. His remarks were the fullest public account to date of the origins of an F.B.I. investigation that continues to shadow the Trump administration.
President Trump told Russian officials in the Oval Office this month that firing the F.B.I. director, James B. Comey, had relieved “great pressure” on him, according to a document summarizing the meeting. The conversation reinforces the notion that President Trump dismissed him primarily because of the bureau’s investigation into possible collusion between his campaign and Russian operatives.
Ms. Yates, the former acting attorney general, gave a dramatic account of an unfolding crisis in the early days of President Trump’s White House. Less than a week into the Trump administration, Sally Q. Yates, the acting attorney general, hurried to the White House with an urgent concern. The president’s national security adviser, she said, had lied to the vice president about his Russian contacts and was vulnerable to blackmail by Moscow.
