Grassley's announcement comes after Democrats on the committee called for Trump Jr.'s transcript to be released, including Sens.
In a cover letter to Deputy Attorney General Rod Rosenstein and FBI Director Christopher Wray released by the committee, said the referral relates to "certain communications between Christopher Steele and multiple US news outlets regarding the so-called 'Trump dossier.'" The rest of the referral is classified and was not released. It was not immediately clear when that process will be complete.
What transcripts could be released?
Mr Grassley, the chairman of the committee, is also moving to release all of the panel's interviews relating to the June 2016 Trump Tower meeting between a Russian lawyer and the President's eldest son.
His panel leads one of four Russia-related inquiries into Trump officials.
But Grassley also said the committee has given up in its efforts to speak with Kushner, saying that he would not be testifying before the panel.Grassley blamed the committee's top Democrat, Sen.
He said the release of the documents can "hopefully be done through agreement with the Ranking Member, but if not, possibly through a committee vote". The committee also received a written response to questions from Veselnistkaya it also intends to release.In lieu of talking to Kushner himself, Grassley noted that both Kushner and Manafort spoke with the Senate Intelligence Committee a year ago. "If it's what you say I love it", Trump Jr. responded.Trump Jr. and other meeting participants denied any damaging information was provided, and said Veselnitskaya focused on United States sanctions against Russia at the meeting.The Senate Judiciary Committee said it has interviewed five participants in the meeting, including Goldstone and the three Russians who attended the meeting.
Democrats have used the June 2016 meeting to suggest the president, his son and other members of the campaign team colluded with Russian Federation ahead of the presidential election.
In a letter Wednesday to Inspector General Michael Horowitz, Rep. Jerrold Nadler of NY and Rep. Elijah E. Cummings of Maryland, the ranking Democrats on the House Judiciary Committee and the House Committee on Oversight and Government Reform, respectively, wrote, "It seems obvious that the goal of these attacks is to undermine [special counsel Robert Mueller's] investigation into connections between the Trump campaign and the Russian government".

The survivors say they'll stay united in their efforts to bring more accountability and transparency to the university. Comfort, compassion and understanding for the survivors and our community; togetherness, time and love for my family.
Others attending included Kushner, Trump campaign chairman Paul Manafort and lobbyist and former Soviet counterintelligence officer Rinat Akhmetshin.
Media captionPresident Trump said he is "looking forward" to being questioned Why release transcripts?
Trump Jr. has said that the meeting, which was arranged through publicist Rob Goldstone, primarily focused on U.S. -Russia adoption policies. There are three congressional committees conducting probes of alleged Russian interference in the 2016 elections.
Despite Grassley's supposed frustration with Feinstein's decision to release Simpson's testimony, the GOP committee chairman claims he is now interested in full transparency on those witness testimonies.
"I certainly haven't heard that", she told reporters at the Senate, explaining that Simpson's associates had asked her to release that transcript to counteract what they considered misleading reporting.
"As a result, it looks like our chances of getting a voluntary interview with Mr. Kushner have been shot", he added. A lawyer for Trump Jr. declined comment.
The texts between Federal Bureau of Investigation agent Peter Strzok and Federal Bureau of Investigation lawyer Lisa Page, who were romantically linked, went missing due to an apparent technical glitch and were recovered using forensic tools.
A release from the committee said that the referral, which is based on both classified and publicly available information unearthed by investigators, does not pertain to the veracity of claims in the dossier.
