As Democratic Senator Claire McCaskill's claims that she had never met with Sergey Kislyak were proven to be untrue, six more Democrats have been revealed to have met with the Russian Ambassador.

Senator Mary Landrieu of Louisiana, Maria Cantwell of Washington, Amy Klobuchar of Minnesota, Jack Reed of Rhode Island, Robert Casey of Pennsylvania and Sheldon Whitehouse of Rhode Island sat in on the meeting with Kislyak and McCaskill, Fox News reported.

The seven Democratic leaders met with the ambassador to discuss the blockade of US adoptions in Russia in 2013.

A spokeswoman for Sessions claimed the ex-senator's contact with Kislyak was not unusual because he sat on the Senate's Armed Services Committee at the time. Missouri Sen. Claire McCaskill pushed back on Twitter - her claim was later found to be false

McCaskill's claims were quickly disproved after Charles C.W. Cooke of the National Review discovered tweets saying otherwise

Klobuchar said in a statement that she was at the meeting to tell Kislyak about the families she met in Minnesota.

McCaskill was one of the slew of Democratic lawmakers demanding Attorney Jeff Sessions' head after it was revealed he had met with Kislyak twice last year.

The Missouri senator had denied meeting him saying in her ten years serving on the Armed Services Committee, she was involved in 'no call or meeting' with the Russian diplomat.

Her claims were quickly disproved after Charles C.W. Cooke of the National Review discovered tweets saying otherwise.

'Off to meeting w/Russian Ambassador. Upset about the arbitrary/cruel decision to end all US adoptions, even those in process,' she tweeted on January 2013.

That same year in August, McCaskill tweeted again: 'Today calls with British, Russian and German Ambassadors re: Iran deal. #doingmyhomework.'

She told USA Today the meeting was with around a dozen other senators.

She said: 'The Russian ambassador has never called me.

'The Russian ambassador has never requested a meeting. I have never met with the Russian ambassador one-on-one.'

Among the Democratic leaders calling for Sessions's resignation, House Minority Leader Nancy Pelosi was also accused of meeting with Kislyak in the past after she had denied meeting him.

President Donald Trump went after Democratic Senator Charles Schumer by retweeting this photo of Schumer and Russian President Vladimir Putin

President Trump demanded an 'investigation' of House minority leader Nancy Pelosi after a photo emerged showing her seated at a table with the Russian ambassador to the U.S.

On Thursday, Attorney General Jeff Sessions recused himself from any investigations involving the presidential election after it was revealed he twice met the ambassador during the campaign.

WHAT SESSIONS SAID WHICH STARTED LIES ROW - AND COULD COST HIM HIS JOB During Jeff Session's Attorney General confirmation hearing on January 10 he was questioned about the Trump campaign's relations with Moscow. Sen. Al Franken: 'If there is any evidence that anyone affiliated with the Trump campaign, communicated with the Russian government in the course of this campaign, what would you do? Jeff Sessions: 'Sen. Franken, I'm not aware of any of those activities. 'I have been called a surrogate at a time or two in that campaign and I did not have communications with the Russians.'

Pelosi appeared to give a gift to the Trump White House, which has been sent reeling by reports of Trump's Russia ties, when she fielded a question about at a Politico interview Friday about whether she had ever met the current Russian ambassador, Sergey Kisliak.

'Not with this Russian ambassador, no,' was Pelosi's response.

Within hours, a photo surfaced showing Pelosi seated around the same table as the peripatetic ambassador. Trump called for an investigation on the Democratic leader on Twitter.

Pelosi's spokesman, Drew Hammill, told Politico, which published the photo, that Pelosi had meant she'd never met solo with the ambassador.

Donald Trump also called for an investigation of Senator Chuck Schumer after tweeting an old photo of Schumer and Russian President Vladmir Putin smiling and eating doughnuts.

The 2003 photo was taken in New York, as Schumer welcomed Putin for an event commemorating Lukoil's first gas station in Manhattan, Gateway Pundit revealed.

Schumer had said at a press conference and on Twitter, 'DOJ must appoint a special prosecutor who is beyond reproach, completely impartial, w/out any significant ties to either political party.'

On Saturday, protesters gather outside of the Russian Embassy in Washington D.C. to march against Donald Trump and the government ties with Russia.

Attorney General Jeff Sessions said Thursday morning that while he twice met with Russia's ambassador during the presidential campaign season, he was speaking with him in his capacity as a senator, not as a campaign adviser to Donald Trump

The Trump administration has come under fire for Russia contacts, at a time when the Kremlin was under sanction following the country's invasion of Ukraine.

DEMOCRAT SENATOR GOING AFTER SESSIONS WASN'T TRUTHFUL EITHER Missouri Democratic senator Claire McCaskill lead the charge against Sessions - saying she had never met the Russian ambassador. But that position was contradicted by her own Twitter account. It showed that she had met him once and called him once. Surprisingly, McCaskill brazened out the apparent hypocrisy. She told USA Today the meeting was with around a dozen other senators. And she said: 'The Russian ambassador has never called me. 'The Russian ambassador has never requested a meeting. I have never met with the Russian ambassador one-on-one.' Advertisement

In 2003, at the time the Schumer meeting occurred, Putin had not yet fully emerged into his role as perpetual adversary to U.S. policy goals. In 2001, President George W. Bush famously said after meeting Putin, 'I found him to be very straightforward and trustworthy. We had a very good dialogue. I was able to get a sense of his soul.'

In the intervening years Putin cracked down on the free press, helped engineer his departure and return to power, put down a rebellion in Chechnya, and interfered in the politics of its neighbors.

The U.S. intelligence community has concluded that Russia hacked the U.S. elections.

Schumer has called for a special prosecutor to investigate Trump Russia ties and whether an investigation has already been compromised. He has called on Attorney General Jeff Sessions to resign, and was among the first to call for Sessions to recuse himself from any investigation – something Sessions did on Thursday in a dramatic announcement.

'Because the Department of Justice should be above reproach, for the good of the country, Attorney General Sessions should resign,' Schumer said.

In addition to Kushner, former national security advisor Mike Flynn met with Russia's ambassador.

The Daily Caller reported at least 22 visits by ambassador Sergey Kislyak to the White House during the Obama administration.

The number of advisors linked to President Donald Trump who met with Russia's ambassador to the U.S. has grown to five – with two more acknowledging the contacts Thursday night.
