President Trump argued in a pair of tweets Monday evening that the House Intelligence Committee should look a deal between a Russian state-owned energy company, Rosatom, and a Canadian-owned mining company with deep ties to the Clinton Foundation that had ultimately placed one-fifth of U.S. uranium interests in Russian hands.

In one of the tweets, Trump asserted that stories about his campaign's alleged connection to Russian officials are a "hoax."

"Why isn't the House Intelligence Committee looking into the Bill & Hillary deal that allowed big Uranium to go to Russia, Russian speech....," he wrote in one tweet.

He continued: "...money to Bill, the Hillary Russian "reset," praise of Russia by Hillary, or Podesta Russian Company. Trump Russia story is a hoax. #MAGA!"

The deal with Uranium One, the Canadian company owned by Clinton Foundation patron Frank Giustra, plagued Hillary Clinton throughout the presidential race as an example of the ways her family's foundation could have served as a conduit for larger financial and political interests. The transaction that left so much of America's uranium production under the control of a Canadian company with extensive Clinton ties took place while Hillary Clinton served as secretary of state and required the approval of an inter-agency committee that included the State Department.

Trump and his White House team have spent weeks fending off allegations of inappropriate connections between the Trump campaign and Russian intelligence officials. Critics have maintained that Trump or his top advisors colluded with Russian officials to steal and leak emails from the inboxes of high-ranking Democrats in the Clinton campaign and on the Democratic National Committee. No evidence has emerged to support those allegations.

The president's tweets Monday evening referenced the House Intelligence Committee's probe into Russian cyber activities during the presidential race. The Senate Intelligence Committee and the FBI are both looking into those activities.
