President Donald Trump is trying to divert attention from the possibility of improper connections to Russia by his campaign aides as he attempts to shift the focus onto 2016 Democratic presidential nominee Hillary Clinton.

In a series of tweets from his personal account Monday night, Trump said the "Trump Russia story is a hoax." He argued that it is Clinton, the former secretary of state under President Barack Obama, who has many questions to answer regarding her own links to Russia and her husband Bill Clinton's connections to the Kremlin.

Trump tweeted, "Why isn't the House Intelligence Committee looking into the Bill & Hillary deal that allowed big Uranium to go to Russia, Russian speech...money to Bill, the Hillary Russian 'reset,' praise of Russia by Hillary, or Podesta Russian Company. Trump Russia story is a hoax."

With these tweets and little or no explanation of what he was talking about, Trump seemed intent on muddying the situation. Trump seemed to be arguing that Hillary Clinton allowed uranium to be transferred to Russia while she was secretary of state. This appears to be based on Russia's nuclear power agency buying a controlling interest in a Toronto-based company which has mines and other facilities in the United States. This deal was considered by several U.S. agencies and had to be approved by the President Barack Obama before it went through. Trump also was referring to the Obama administration's declared intention during its early months to "reset" the U.S. relationship with Russian President Vladimir Putin.

The FBI is investigating potential links between Trump campaign aides and the Russian government, possible collusion between the two, possible attempts by the Kremlin to get involved in the 2016 election to defeat Clinton and elect Trump, and overall surveillance practices.

In another development, Jared Kushner, Trump's son-in-law and a presidential adviser, met with the head of a Russian bank linked to Putin's government, according to CNN.

And House Intelligence Committee Chairman Devin Nunes, R-Calif., remained under fire from Democrats who said he was trying to defend Trump and not conduct a fair committee investigation of alleged collusion between Trump's aides and the Russians to facilitate Russian meddling in the election. House Democratic Leader Nancy Pelosi, D-Calif., Senate Democratic Leader Chuck Schumer, D-N.Y., and Rep. Adam Schiff, D-Calif., the top Democrat on the House Intelligence Committee, called on Nunes to recuse himself from the committee's investigation into Russian connections.

Beyond this, Trump again attacked the House Freedom Caucus, a group of three dozen ultraconservatives, for their role in blocking a Trump-backed bill to repeal and replace the Affordable Care Act, Obama's signature health-care initiative. The bill failed to attract a majority of votes in the Republican-controlled House, and GOP leaders withdrew it from consideration on Friday in a major setback for the president and House Speaker Paul Ryan, R-Wis.

Trump tweeted, "The Republican House Freedom Caucus was able to snatch defeat from the jaws of victory. After so many bad years they were ready for a win!"

He also wrote on Twitter, "The Democrats will make a deal with me on healthcare as soon as Obamacare folds--not long. Do not worry, we are in very good shape."

But Trump has been tanking in the polls. Gallup's latest tracking survey finds that only 36 percent of Americans approve of his job performance, his lowest rating so far, and 57 percent disapprove.
