Senator and presidential candidate Rand Paul, R-Ky., told Fox News' "Fox and Friends" on Monday that he would like to see a congressional investigation into whether foreign donations to the Clinton Foundation influenced Hillary Clinton's actions while head of the State Department.

"I've talked to people within the Senate about whether there will be an investigation," Paul said, reported The Washington Times. "I favor an investigation of this, because we need to know that. If you're going to elect someone to President of the United States, whether they've been accepting gifts that might influence their opinion."

He continued: "The presidency is the commander-in-chief, you have to have trust in your commander-in-chief that they wouldn't actually sell the country while they're the commander-in-chief," Paul said. "Secretary of State is an incredibly important position, she got to be on the approval of whether or not a uranium company was sold to Russia, and she allowed it to happen while receiving money from the shareholders."

In the past week, former Secretary of State Clinton, who is also the 2016 Democratic presidential favorite, has been accused of using her State Department to approve a Russian takeover of one of America's largest uranium mines in exchange for $2.35 million in donations to her family charity by an associated shareholder.

Former Massachusetts Gov. Mitt Romney said last week that it "looks like bribery." When Paul was asked whether he thought the same, he responded that he thinks it "has the appearance of impropriety."

Clinton's campaign team has called the reports right-wing conspiracy theories that lack evidence of an explicit trade-off, also claiming that Clinton herself was not involved in the State Department's review of the uranium deal. Rather, there were eight other agencies involved in the government's review of the deal, her team said.

"So, in order for the Russians to buy this group, it had been to be approved by Hillary Clinton," Paul stated earlier, according to Breitbart. "Now, she says 'well, I didn't actually do anything.' But it has to be a unanimous vote, had she stood up and objected, the sale wouldn't have gone through. But now, the Russians own 20% of our mining. And then it turns out that the people who own the mining company were giving over a hundred million dollars to the Clinton Foundation."
