"We're not going to jump to any conclusions at this time", Nunes said.
Democrats are criticizing both investigations as attempts to distract from the ongoing investigation into Russia's election meddling and possible collusion with the Trump campaign, according to ABC News.
Republicans in Washington have announced an investigation into a uranium deal with Russian Federation negotiated by the Obama administration. Nine government agencies and a number of federal and state regulators approved the uranium deal. "Me and President Obama, we are the ones they like to put in the crosshairs", Clinton said.
"Our justice system is represented by a blind-folded woman holding a set of scales", the two chairmen said in a statement.
In 2010, a Canadian company called Uranium One, which had mining stakes around the world, was bought by Rosatom, a state-owned Russian corporation, giving Rosatom oversight of one-fifth of USA uranium production.
President Donald Trump and other Republicans have accused the Russian uranium company of donating to the Clinton Foundation in an effort to sway Clinton to sign off on the deal, though the allegations are unproven.
The Committee on Foreign Investment in the United States (CFIUS) approved the deal, and Russian Federation later took over Uranium One.
Rep. Devin Nunes said at a news conference that his committee and the House oversight committee are launching the joint investigation into the uranium deal, whether there was an FBI investigation into the matter and, if so, why Congress wasn't informed.
Allegations surrounding the uranium deal resurfaced this past week when The Hill reported the FBI was investigating the donations and did not inform Congress. It was negotiated under the administration of President Barack Obama.
In launching this new investigation, Nunes is adding congressional muscle to a right-wing narrative that has cast Clinton as cozying up to Russian Federation.
The investigation centres on Rosatom, the state-owned Russian nuclear energy company, which began buying shares in Uranium One - a Toronto based enterprise with interests in the USA - in 2009.
Grassley claims that the DOJ, under Obama, "threatened" the informant with prosecution "if he disclosed details of his involvement in the investigation".
"The current Russian investigation is about the election".
"Seven years ago this month, I raised these objections with the treasury secretary who said they were being fully investigated and we want to see what happened to that inquiry", said King.
