 Keith Schiller  told the House Intelligence Committee on Tuesday that  he  rejected the offer from the man  who appeared to be Russian or Ukranian  according to two people familiar with the discussion.  He  quickly dismissed what appeared to be a suggestion of procuring prostitutes for Trump  they said.
âNo  man  weâre not interested in that â  Schiller  told the man  the people said.
The offer came at the end of a late-morning planning meeting that  Schiller  attended when  he  accompanied Trump to Moscow for the annual Miss Universe pageant  which was produced by a company that Trump owned.
 Schiller   Trumpâs longtime bodyguard who frequently accompanied him on trips  told congressional investigators that he saw no compromising  illicit or illegal behavior by Trump while in Moscow  according to the people.
The offer to send women to Trumpâs room came after  Schiller  said  he  attended a meeting in Moscow with about 15 people to discuss details of the pageant. Among those in attendance were Russian pop star Emin Agalarov and his father  Aras Agalarov  a business magnate with close ties to the government of President Vladimir Putin  according to the people familiar with his interview.
As the meeting broke up   Schiller  said a man  he  did not know approached  him  and asked if  he  would like five women to visit Trump at  his  hotel room later that night   he  told investigators.
 Schiller  told the committee that  he  joked about the offer with Trump later that evening as they headed back to their hotel  the people said.
âCan you believe one of these guys wanted to send some women up to your room?â  Schiller  recalled saying.
An attorney for the Agalarovs said they had no knowledge of the offer to  Schiller .
âCategorically  neither one of them has any knowledge of that happening â said Scott Balber  a lawyer for Emin and Aras Agalarov. âThey didnât do  it   they didnât hear  it   and they have no reason to believe  it âs true.â
A White House attorney did not immediately respond to a request for comment. An attorney for  Schiller  declined to comment on the details of his interview.
NBC News first reported that the House Intelligence Committee asked  Schiller  for details about the episode.
 Schiller âs long and close relationship with Trump makes  him  a potentially valuable witness to investigators examining Russiaâs meddling in the 2016 election. The former director of security at the Trump Organization joined Trump at the White House  serving as director of Oval Office Operations until September.
In his House interview   Schiller  said  he  traveled as many as five and six days a week with Trump when the businessman ran the Trump Organization  adding that he could not remember the precise details of all their trips.
 Schiller  told investigators that  he  and Trump stayed at a luxury hotel during their 2013 Moscow trip  although  he  said  he  could not recall its name.  He  said  he  was not certain if  he  stayed on the same floor as Trump  although  he  acknowledged that they usually had adjoining rooms.

As part of the 9th annual Freedom Conference & Festival , a conservative confab taking place in Steamboat Springs next month , the paintings of 43rd President George W. Bush will be on display for attendees at the Steamboat Grand Hotel . 
"This is the first time the -LRB- Bush -RRB- exhibit has been shown in Colorado , giving state residents a unique opportunity to view this popular collection ," wrote Jackson Shedelbower , of the Steamboat Institute , in an email . 
The one-day exhibition on Friday , Aug. 25 , organized by the Steamboat Institute , marks the Colorado debut of Bush 's work from "The Art of Leadership : A President 's Personal Diplomacy" exhibition , which features paintings of world leaders Bush met during his tenure in the White House including Vladimir Putin , Angela Merkel , Hamid Karzai , Ellen Johnson Sirleaf and Tony Blair . 
Although some balked at the idea of Bush as a fine artist when he took up painting in his post-presidential retirement , the 71-year-old has stuck to his guns and humbly worked to improve his art . 
"Portraits of Courage : A Commander in Chief 's Tribute to America 's Warriors ," a book of Bush 's paintings of wounded U.S. military veterans that was published in February , netted surprisingly favorable reviews from critics and topped The Washington Post 's best-selling books list earlier this year . 
"-LRB- Bush -RRB- was really putting himself out there and taking a personal risk with these paintings , not knowing what people would think of them ," said Jennifer Schubert-Akin , CEO of the free-market , nonprofit Steamboat Institute . 
Bush will personalize a copy of the book that is being auctioned on the Steamboat Institute 's fundraiser as part of its $ 75-per-person Red , White & Blue Bash fundraiser on July 20 , Schubert-Akin said , with bidding starting at $ 300 .

[Q]: BOSTON (Reuters) - More than half a century after  U.S. President John F. Kennedy  was struck down by an assassinâs bullet in Dallas  Texas  the United States is due on Thursday to release the final files on the investigation into the killing that rattled a nation.

Academics who have studied  Kennedy âs slaying on Nov. 22  1963  said they expected the final batch of files to offer no major new details on why Lee Harvey Oswald gunned down the first and only Irish-American Roman Catholic to hold the office.
They also feared that the final batch of more than 5 million total pages on the  Kennedy  assassination held in the National Archives will do little to quell long-held conspiracy theories that the 46-year-old presidentâs killing was organized by the Mafia  by Cuba  or a cabal of rogue agents.
Thousands of books  articles  TV shows and films have explored the idea that  Kennedy âs assassination was the result of an elaborate conspiracy. None have produced conclusive proof that Oswald  who was shot dead a day after killing Kennedy  worked with anyone else  though they retain a powerful cultural currency.
âMy students are really skeptical that Oswald was the lone assassin â said Patrick Maney  a professor of history at Boston College. âItâs hard to get our minds around this  that someone like a loner  a loser  could on his own have murdered  Kennedy  and changed the course of world history. But thatâs where the evidence is.â

In 1992  Congress ordered that all records relating to the investigation into  Kennedy âs death should be open to the public  and set a final deadline of Oct. 26  2017 for the entire set to be made public.
 Kennedy âs assassination was the first in a string of politically motivated killings  including those of  his  brother Robert F. Kennedy and civil rights leader Martin Luther King Jr.  that stunned the United States during the turbulent 1960s.  He  remains one of the most admired U.S. presidents.
