[EX Q]: [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.

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.

[EX Q]: On October 22   Tesla  announced a landmark agreement to manufacture cars in China  building capacity to produce locally and boost sales in the worldâs largest market for electric vehicles.
The agreement is a landmark deal in several respects. China has granted  Tesla  more autonomy than other foreign producers.  Tesla  is the first major foreign automaker to establish local operations without a 50:50 local joint venture partner. This is a key concession as  it  allows  Tesla  tighter control over both  its  intellectual property and vertically-integrated production process.  Tesla  will also benefit by reducing production costs for cars sold in China and  though details were not disclosed  may also receive tax breaks and subsidies akin to those enjoyed by Chinese producers.
 Attracting Tesla  is a symbolic win for China. China has clear ambitions to lead the world in electric vehicles in a broader effort to build a cleaner  environmentally-conscious society. The timing of this announcement during Chinaâs critical 19th Congress reinforces the governmentâs broader objectives.
Yet  a closer look suggests that  Tesla  needs China more than China needs  Tesla . As the chart from IHS Markit: Light Vehicle Forecast below shows  China is an essential market for leading global automakers. China surpassed the United States in 2009 as the largest car market  and car sales in Western markets are forecast to decline  while emerging markets will drive global growth.
With its recent shift in environmental priorities  China is also becoming a major player in electric vehicles. In 2016  China accounted for 45% of all the newly registered electric vehicles worldwide with 336 000 in China vs. 160 000 in the United States. China is also building an EV charging infrastructure that primes the market for a high-end producer such as  Tesla . In 2016  China had a 44% global share of publicly available EV charging outlets  including 82% of fast-charging outlets. Demand for electric vehicles has grown faster in China than in any other global market with the share of EV purchases increasing 3.6x from 2014 to 2016. With EV purchases accounting for just 1.37% of the total car market  the Chinese EV market seems poised for further growth.
Low end EV's dominate Tesla
Despite seemingly favorable market conditions   Tesla  has had little success in China to date. Subsidies have driven electric vehicle demand  with the Chinese government paying up to 50% of the purchase price of domestically-produced EV cars. Lower-end electric vehicles have dominated  and  Tesla   which is subject to 25% import taxes  has largely been priced out of the market. In 2016   Tesla  had just a 3% share of the electric vehicle market in China.
 Tesla âs lackluster performance in China is a striking contrast to other global automakers. As in the West  cars are a status symbol in China  and consumers prefer prestigious global brands. Foreign cars claim a 60% market share in China  with foreign brands claiming seven of the top eight spots for cars sold in 2016. Premium brands have done particularly well in China.
Audi  BMW  Mercedes and Porsche all sell between a quarter to a third of their total global sales in China -- a 10% increase on average in just the past five years. In addition  Volkswagen now sells half of its global volume in China. The experiences of other foreign car brands suggest that  Tesla  should fare well in China if  it  can reduce production costs and vehicle pricing in line with the local market.
It is within this context that  Tesla  needs China more than China needs  Tesla . Chinaâs electric vehicle market will grow with or without  Tesla . But Teslaâs deal with the Shanghai government is both timely and essential. As the electric vehicle market takes off in China   Tesla  must do well in this vital market to maintain global leadership. Building volume in China is required to reduce production costs and pricing in the global as well as local market. Ultimately  as we are seeing in other industries   Tesla  may find that technology talent in China will also prove vital to maintain  its  position as a leading innovator globally.
