US President Donald Trump's son-in-law and top aide Jared Kushner will appear before a Senate panel investigating Russian interference in the US election, the White House has said.
Mr Kushner, who is married to Mr Trump's daughter Ivanka, was the president's main intermediary with foreign governments during the campaign and now plays that role in the White House.
He arranged meetings between Mr Trump and leaders from Japanese Prime Minister Shinzo Abe to Mexican President Enrique Peña Nieto.
But it is his contacts with Russian officials that are now coming under the microscope, amid explosive allegations of collusion between the Trump campaign and the Kremlin.
Allegations by US intelligence agencies that Russian actors were behind hacking of senior Democratic Party operatives and spreading disinformation linger over Mr Trump's young presidency.
Democrats charge the Russians wanted to tilt the election toward the Republican, a claim dismissed by Mr Trump. Russia denies the allegations.
But there has been no doubt that the Russian ambassador to the United States, Sergei Kislyak, developed contacts among the Trump team.
Mr Trump's first national security adviser, Michael Flynn, was forced to resign on 13 February after revelations that he had discussed US sanctions on Russia with Kislyak and misled Vice President Mike Pence about the conversations.
Executives of Russian state development bank Vnesheconombank (VEB) had talks with Mr Kushner during a bank road show in 2016 when it was preparing a new strategy, the bank said.
"As part of the preparation of the new strategy, executives of Vnesheconombank met with representatives of leading financial institutes in Europe, Asia and America multiple times during 2016," VEB said in a statement.
It said road show meetings took place "with a number of representatives of the largest banks and business establishments of the United States, including Jared Kushner, the head of Kushner Companies."
There was no immediate comment from Mr Kushner.
In an article posted on 18 December, Forbes estimated that Mr Kushner, his brother Josh and his parents, Charles and Seryl, have a fortune worth at least $1.8 billion, more than half of which Forbes estimates is held in real estate.
Forbes did not provide a specific estimate for Jared Kushner’s net worth on his own.
VEB declined to say where the meetings took place or the dates.
US officials said that after meeting with Mr Kislyak at Trump Tower last December, a meeting also attended by Mr Flynn, Mr Kushner met later in December with Sergei Gorkov, the CEO of Vnesheconombank.
White House spokeswoman Hope Hicks confirmed the meetings.
White House Press Secretary Sean Spicer has told reporters that Mr Kushner is willing to testify to the Senate Intelligence Committee chaired by US Senator Richard Burr, a North Carolina Republican.
"Throughout the campaign and the transition, Jared served as the official primary point of contact with foreign governments and officials ... and so, given this role, he volunteered to speak with Chairman Burr's committee, but has not received any confirmation regarding a time for a meeting," Mr Spicer told reporters.
The Republican and Democratic leaders of the Senate panel also said Mr Kushner had agreed to be interviewed.
Simply meeting with representatives of a US-sanctioned entity is not a violation of sanctions or against the law.
