PROBLEM: [Hereâs what we know so far about Team Trumpâs ties to Russian interests]
Trump had received private assurances from then-FBI Director James B. Comey starting in January that he was not personally under investigation . Officials say that changed shortly after  Comeyâs  firing.
Five people briefed on the interview requests  speaking on the condition of anonymity because they were not authorized to discuss the matter publicly  said that Daniel Coats  the current director of national intelligence  Mike Rogers  head of the National Security Agency  and  Rogersâs  recently departed deputy  Richard Ledgett  agreed to be interviewed by Muellerâs investigators as early as this week. The investigation has been cloaked in secrecy  and it is unclear how many others have been questioned by the FBI.
The White House now refers all questions about the Russia investigation to Trump âs  personal attorney  Marc Kasowitz.
The obstruction-of-justice investigation of the president began days after  Comey  was fired on May 9  according to people familiar with the matter. Muellerâs office has taken up that work  and the preliminary interviews scheduled with intelligence officials indicate that his team is actively pursuing potential witnesses inside and outside the government.
[Inside Trumpâs anger and impatience â and his sudden decision to fire  Comey ]
The interviews suggest that Mueller sees the question of attempted obstruction of justice as more than just a â he  said   he  saidâ dispute between the president and the fired FBI director  an official said.
 Comey  confirmed publicly in congressional testimony on March 20 that the bureau was investigating possible coordination between the Trump campaign and the Russians.
Comeyâs statement before the House Intelligence Committee upset Trump  who has repeatedly denied that any coordination with the Russians took place. Trump had wanted  Comey  to disclose publicly that  he  was not personally under investigation  but the FBI director refused to do so.
Coats told associates that Trump had asked him whether Coats could intervene with  Comey  to get the bureau to back off its focus on former national security adviser Michael Flynn in its Russia probe  according to officials. Coats later told lawmakers that he never felt pressured to intervene.
Republican lawmakers seized on Comeyâs testimony to point out that Trump was not in the FBIâs crosshairs when  Comey  led the bureau.

PROBLEM: Sam Querrey gave the United States a winning start in its bid to reach Saturday's final at the World Team Cup.
 Querrey beat Jan Hajek 6-3  7-5 on Thursday to put the U.S. 1-0 up against the Czech Republic in the Red Group and remain unbeaten in his three singles this week.
 "So far so good " said Querrey. "I thought today was the best I played out of the three matches. So I'm pretty excited."
 Hajek claimed the first break  when Querrey ended a long rally with a forehand error  to go 3-1 up but the American player responded by winning the next five games in a row to take the opening set.
 Both players saved a break point late in the second set before Querrey broke at 6-5  converting his third match point.
 "I've been working this week to try and hit my forehand a little bigger. I felt I did that today " said Querrey. "I felt pretty much anytime I got a forehand  I was able to take control of the point."
 Querrey said his win takes the pressure off the U.S. ahead of Friday's matches.
 "A little bit  yes. I think John (Isner) can go out there and play a little more freely  which is a good thing " Querrey said. "When we have the lead  you can swing away a little bit more than if we were 1-0 down.
 "Then  the Bryan brothers  we expect them to win every match. Hopefully  they are going to do that again."

SOLUTION: Sam Querrey

PROBLEM: Stewart tells O ' Reilly he ' s voice of sanity on Fox
The host of "The Daily Show" and Fox's kingpin exchanged some good-natured shots Wednesday during Stewart's appearance on a network he relishes mocking. Stewart tossed off jokes but also criticized Fox for being a "cyclonic perpetual motion machine" opposing President Barack Obama.
"They have taken reasonable concerns about this president and this economy and turned it into a full-fledged panic attack about the next coming of Chairman Mao " Stewart said.
Both men have appeared on each other's show before  but it was Stewart's first time back since 2004. O'Reilly annoyed Comedy Central by calling Stewart's audience primarily "stoned slackers"; on Wednesday  he amended it to "stoned slackers who love Obama."
There was even a dispute over who initiated the return visit. O'Reilly said on Fox earlier Wednesday that Stewart's representatives had asked for him to come on the show. Comedy Central spokesman Tony Fox said an O'Reilly producer requested the appearance.
Fox "is the most passionate and sells the clearest narrative of all the news networks  if ... you're still referring to it in that manner " Stewart said.
O'Reilly pointed out that Fox is like a newspaper with news and opinion pages  an idea Stewart poked fun at.
Stewart was asked about a Washington Post column that suggested he was becoming disenchanted with Obama. "I don't take any of that seriously " he said.
But he did criticize Obama for not taking control of his agenda.
"It allows too much room for different narratives to take hold  for instance  a narrative that might emanate from a news organization of this ilk " he said.

SOLUTION:
Stewart
