The Dow Jones Industrial Average was down 47.81 points, or 0.23 percent, to 21,136.23.
The day after President Donald Trump asked James B. Comey, the FBI director, to end an investigation into his former national security adviser, Comey confronted Attorney General Jeff Sessions and said he did not want to be left alone again with the president, the New York Times reports, citing current and former law enforcement officials. Two days earlier, Comey had confirmed in a congressional hearing that the bureau was probing whether Trump's campaign coordinated with Russian Federation during the 2016 race.
The United Arab Emirates (UAE), along with Saudi Arabia, Bahrain and Egypt earlier this week cut diplomatic ties with Qatar, accusing the Gulf state of supporting and financing "terrorism" as well as interfering in their internal affairs.
Officials speaking on the condition of anonymity told the Post that after discussing the conversation with other officials, Coats decided that intervening as Trump had asked would be inappropriate.
Trump announced in January that he was nominating Coats to serve as DNI, an office which is responsible for overseeing US intelligence agencies and for briefing the president on global developments. "The last time he testified under oath, the Federal Bureau of Investigation had to scurry to correct the testimony, " adviser Kellyanne Conway said earlier this week.
The appearance will mark Comey's first public comments since Trump abruptly fired him last month.
Two legal experts said Comey would seek to avoid compromising a new inquiry led by Special Counsel Robert Mueller or separate congressional investigations.
"I expect us [committee members] to ask him to be sure that we get all of the answers we need, not just the answers he [Comey] wants to give", said Republican Senator Roy Blunt of Missouri.
Comey is scheduled to testify Thursday before the Senate intelligence committee.
Trump fired Comey on May 9, a step that stunned Washington and intensified scrutiny of the matter.
The report is based on what is described as a "source familiar with Comey's thinking", according to the story.
Costa says White House staffers have told him that Trump has largely forgone planning and strategizing around Comey's testimony, planning to just warm up his tiny thumbs and take to his phone instead. In other words, while each episode could be seen as a "ham-handed misstep", the sum of the actions - capped by the Comey firing - could become something much more serious, especially after the President told NBC that he was thinking of the Russian Federation investigation when he made the decision to dismiss Comey. Some of the commentary in it - including the title - echoes public statements by Trump and other administration officials.
Asked about the testimony, Trump on Tuesday was tight-lipped: "I wish him luck", he told reporters before a meeting with lawmakers.
White House officials had considered trying to invoke the President's executive privilege authority to block the testimony, but they said on Monday that they would not do so.
According to Comey's memo, Trump told Comey, "I hope you can see your way clear to letting this go, to letting Flynn go".
