Russia has reportedly recalled ambassador to the United States Sergey Kislyak -- an official at the center of probes into possible collusion between Russia and President Donald Trump's former campaign.
BuzzFeed News reported the Kislyak development out of Russia on Sunday, citing three sources who confirm the ambassador is being recalled to Russia as the controversy over his country's involvement in the 2016 election grows.
Kislyak, who has been in his post since 2008, reportedly participated in undisclosed meetings with Attorney General Jeff Sessions and former national security adviser Michael Flynn -- sparking a recusal in the Russia investigation from Sessions, and the resignation of Flynn.

The former senior Trump campaign official and White House adviser was present and crucial during the firings of Michael Flynn and James Comey.
The former head of the Trump transition team following the 2016 election has said previously that he believes he was fired due to his opposing the hiring of Michael Flynn as national security adviser.
Former U.S. senator Jeff Sessions from Alabama joined Trump's campaign as a foreign policy adviser in February 2016. Sessions was nominated to be U.S. attorney general by President Trump and was then confirmed by the Senate. Reports then emerged that Sessions had spoken twice with Sergey Kislyak while he was senator -- a fact that he left out of his Senate hearing testimony. Instead, he said in writing that he had not communicated with any Russian officials during the campaign season. Sessions defended himself saying he had spoken with Kislyak specifically in a senate capacity.
Paul Manafort signed on as Donald Trump's campaign manager in March 2016. A longtime Republican strategist and beltway operative, Manafort had previously served as an adviser to former Ukrainian president Viktor Yanukovich -- a pro-Russia leader who was violently ousted in 2014. Manafort resigned from his campaign position in August 2016 amid questions over his lobbying history in Ukraine for an administration supportive of Russia. The former campaign manager reportedly remained in Trump's circle during the post-election transition period.
Gen. Michael Flynn was named President Trump's national security adviser in November of 2016. Flynn reportedly met and spoke with Russian Ambassador Sergey Kislyak in December, at one point discussing sanctions. Flynn originally told Vice President Pence he did not discuss sanctions -- a point the Department of Justice said made the national security adviser subject to blackmail. Flynn resigned from his position in February.

Stone is a longtime Republican political consultant who served as a campaign adviser to Trump who continued to talk with the then-GOP candidate after stepping away from his adviser role. Stone claimed last year that he had knowledge of the planned WikiLeaks release of emails pertaining to Hillary Clinton and the Democratic National Committee. Stone recently admitted to speaking via direct message with "Guccifer 2.0" -- an online entity U.S. officials believe is tied to Russia. Stone says the correspondence was “completely innocuous.”
Page worked for Merrill Lynch as an investment banker out of their Moscow office for three years before joining Trump's campaign as a foreign policy adviser. During his time with Merrill Lynch, Page advised transactions for two major Russian entities. Page has called Washington "hypocritical" for focusing on corruption and democratization in addressing U.S. relations with Russia. While Page is someone Trump camp has seemingly tried to distance itself from, Page recently said he has made frequent visits to Trump Tower.
Before Gordon joined the Trump campaign as a national security adviser in March 2016, he served as a Pentagon spokesman from 2005 through 2009. Like others involved in Trump-Russia allegations, Gordon met with ambassador Kislyak in July at the Republican National Convention, but has since denied any wrongdoing in their conversation. He advocated for and worked to revise the RNC language on and position toward Ukraine relations, so it was more friendly toward Russia's dealings in the country.

Caputo resigned from being a Trump campaign communications advisor after appearing to celebrate the firing of former campaign manager Corey Lewandowski. Denying any contact with Russian officials during the 2016 campaign, Caputo did live in Moscow during the 1990s, served as an adviser to former Russian President Boris Yeltsin and did pro-Putin public relations work for the Russian conglomerate Gazprom Media.
