The far end of both the political left and right often causes problems for the Republican and Democratic Party. When it comes to the extreme end of the liberal spectrum, it appears President-elect Donald Trump might have found an ally.

Trump on vaccines

Over the year and half that he was on the campaign trail, Donald Trump would routinely come under fire for his controversial comments, actions, and policy proposals. Whether it was referring to illegal immigrants from Mexico as "rapists" and "murderers," to being open to a Muslim ban, or his praise of Russia and President Vladimir Putin, Trump was never far from critical backlash.

One area that didn't get as much reaction was his stance on mandatory vaccinations, which many on the far-left believe, without evidence, causes autism and other diseases. One prominent name that is against vaccinations is Robert F. Kennedy Jr. who, as reported by Vox on January 10, will meet with Trump to discuss the issue on Tuesday.

Originally reported by Jonathan Lemire of the Associated Press, Donald Trump is getting ready to meet with Robert F. Kennedy Jr. to further discuss the fringe controversy surrounding vaccinations. While the medical community is overwhelmingly on the side that supports vaccinations, conspiracy theories have increased in recent years, despite the lack of credible evidence.

In the past, Kennedy has expressed his concern that the United States government is taking part in a conspiracy and cover-up where they are hiding the link between mental and medical issues linked back to vaccines.

The origin of the conspiracy theory that vaccines cause autism and other issues stem from a study done by Dr.

Andrew Wakefield in 1998. The research and results have long been debunked, and Wakefield, based out of the United Kingdom, has since lost his medical license. Despite this, Donald Trump pushed the issue during a Republican primary debate in 2015. "Just the other day, two years old, a beautiful child, went to have the vaccine," Trump said on stage, before claiming the girl "came back and a week later got a tremendous fever, got very, very sick, now is autistic."

Moving forward

Ever since winning the election, Donald Trump has held multiple meetings with controversial individuals.

Adding vaccine conspiracy theorist Robert F. Kennedy Jr. to the list is an odd choice considering his strong support of fighting climate change, an issue that the billionaire real estate mogul has continued to push back against. Trump will be able to move forward with his agenda after he is sworn into office on January 20.
