The probes, involving the House Judiciary, Oversight and Intelligence Committees, came as Republicans and President Donald Trump weather increasing pressure from the multiple investigations into how Russian Federation may have aided Trump's presidential campaign previous year. "We're not going to jump to any conclusions at this time", House Intelligence Chairman Devin Nunes says. The House Judiciary Committee also launched an investigation with the oversight panel into Obama's Justice Department and Democrat Hillary Clinton's emails.
In addition, President Donald Trump has continued a barrage of complaints about Clinton's involvement in the deal, along with complaints that the mainstream media was not covering the matter, bringing the issue into focus once again.
"I got a letter in response from Treasury Secretary [Tim] Geithner, saying this was getting full scrutiny", said King.
Nunes said the first goal of the investigation, for which the Intelligence Committee is partnering with the House Oversight and Government Reform Committee, is determining "was there actually an open FBI investigation or not".
Clinton was not mentioned during the press conference as part of the Russian Federation investigation.
Russian Federation gradually acquired control of a Canadian mining company-Uranium One-with mining stakes in the United States from 2009 to 2013, a series of agreements that gave it control of 20 percent of America's uranium production capacity.
Other questions the Republican lawmakers said they want addressed revolve around the decision not to file criminal charges against Clinton.
Since uranium is considered a strategic asset, with implications for national security, the deal had to be approved by a committee composed of representatives from a number of United States government agencies.
On Tuesday, the House Intelligence Committee and House Oversight Committee announced yet another Clinton-related investigation - the 2010 sale of a US uranium company to a Russian company, specifically whether there was an FBI probe of the matter and that was approved when Hillary Clinton was secretary of state.
Nunes, who stepped aside from his panel's Russian Federation probe amid controversy in April, said the uranium inquiry was a separate matter. She said at the very least Sessions should lift an Obama-era gag order on a witness who claims he has information about efforts to bribe the Clintons in regard to the deal. He claimed in October 2016 that Clinton gave uranium to Russian Federation "for a big payment", which the Washington Post later said was inaccurate.
Nunes added that he has not spoken to anyone at the White House on the matter.
