Teacher: Given a document, find the main entity about whom the author is writing. Write the full name if mentioned in the text. Note that URLs in the text have been replaced with [Link].
Teacher: Now, understand the problem? If you are still confused, see the following example:
At least Raheem Morris finally has the name of the Bucs' starting quarterback in the back of his mind.
 He wants to make sure he made the decision with his head and not just his heart.
 That's why Morris declined to name his choice between Byron Leftwich and Luke McCown on Friday until after one last consultation with his coaching staff.
 After that  Morris said  he would inform the owners  then his team before making the eagerly awaited announcement. Players were off Friday  so an announcement could come this morning.
 "We'll have a decision here in the near future " Morris said. "I think we've got to go with who we think gives us the best chance to win.
Solution: Raheem Morris
Reason: Here the main entity is Raheem  Morris since the main topic of the document is about him starting as quarterback.

Now, solve this instance: The planned news conference from Sens. Richard Burr  R-N.C.  and Mark Warner  D-Va.  has been billed as a forum for the two panel leaders to give the public an interim status update on the committee's long-running investigation of allegations that Russia attempted to meddle in the 2016 U.S. elections  and that members of the Trump campaign may have colluded with Kremlin officials to improve their chance of victory. It is one of only a handful of public events the Senate Intelligence Committee has held in the nine months since commencing its probe.
In the course of that investigation  committee members and staff investigators have interviewed several members of the intelligence community and Trump's inner circle  mostly behind closed doors - including former campaign chief Paul Manafort and current senior adviser Jared Kushner  who is also President Donald Trump's son-in-law. They have also spoken with senior executives of social media companies like Facebook and Twitter  which carried many of the Russian-backed ads and falsified accounts that tried to exploit popular divisions in the run-up to the election. The committee is expected to continue those conversations in a public hearing with the tech giants early next month;  Burr  and Warner may share additional information about the social media-focused part of their probe on Wednesday.
The intelligence committee has had unprecedented access to classified files during the course of this investigation  and has spent significantly longer vetting the intelligence community's report than officials took to write it. Though  Burr  has set an aspirational deadline of wrapping up its probe by the end of the year   he  and Warner are not expected to release an interim report on Wednesday  according to sources familiar with their plans.
 Burr   Warner  and the spy chiefs they have called to testify before their panel in occasional public hearings have stressed that the 2016 election likely only emboldened Russia's resolve to meddle in future American elections  using similar tactics. Though 2018 is not a presidential election year  it could prove to be a pivotal contest for Congress - and the primary season begins in March  less than six months away.
