Democrats on Wednesday questioned again whether Attorney General Jeff Sessions was forthcoming with Congress amid news reports  he  killed a suggestion by  former Trump campaign adviser George Papadopoulos  to set up a meeting with Republican candidate Donald Trump and Russian President Vladimir Putin.
"Jeff Sessions concealed his meetings with Russians  and he had an obligation to be more forthcoming about the meeting that involved  Papadopoulos  as well " Connecticut Sen. Richard Blumenthal  a member of the Judiciary Committee  told Manu Raju on CNN.
"In fact  one of the points of question is whether  Papadopoulos  in that charging document where there's a reference to a campaign supervisor was  in fact  talking to Jeff Sessions."
According to charging documents unsealed Monday in Russia special counsel Robert Mueller's probe   Papadopoulos  suggested in a July 2016 meeting that  he  should make efforts to connect Trump with Putin.

[EX Q]: Verify if the sentiment of the following document towards the entity Chris Caldwell is Neutral . These primes are exceedingly rare and sporadic  said Chris Caldwell  a professor of mathematics and statistics at the University of Tennessee at Martin  who studies prime numbers and has written a history of the Mersenne primes.
"Finding a prime is not going to change any theorems in mathematics  but this is a type of prime that has been interesting to mathematicians since several centuries before Christ "  Caldwell  said. Even the ancient Greek mathematician Euclid talked about what would later become the Mersenne primes  he said.
 Caldwell  added that the discovery was akin to breaking a land speed record.
The last few Mersenne primes have been closer to each other than the researchers expected   he  said.
The numbers seem to occur sporadically because researchers don't fully understand the pattern they follow   he  said. "So you expect in any process that appears random to have some close groupings of numbers. But  we  didn't expect to find another one so soon after the last one."
"In the long run   we  hope to use these data to predict how often these occur "  he  added.
