SAN FRANCISCO, July 14 (Xinhua) -- Tesla and SpaceX CEO Elon Musk Saturday denied that he is a top donor to a Republican political action committee dedicated to Republican dominance in Congress.

"Reports that I am a top donor to GOP are categorically false. I am not a top donor to any political party," Musk tweeted.

Musk's denial came in response to a report by thehill.com website earlier in the day that he was one of the top 50 donors to the PAC Protect the House, a committee that works to keep Republicans in control of Congress.

Quoting figures of the Federal Election Commission filings released this week, the report said Musk donated a total of 38,900 U.S. dollars to the Republican political group.

Other high-profile donors also included Microsoft co-founder Paul Allen who gave 100,000 dollars and Houston Texans owner Robert McNair with a donation of 371,500 dollars, said the online report.

As the CEO of electric car company, it said, Musk has spoken out against climate change and reportedly unsuccessfully lobbied U.S. President Donald Trump to slap a tax on carbon.

However, Musk asserted he is not a conservative figure and has a moderate approach to political affairs because he is "both politically independent and surprise-dependant."

"To be clear, I am not a conservative. Am registered independent & politically moderate," he said in a Tweeter post.

"I do not actually see the checks. A nominal annual amount goes out automatically to both parties to maintain dialogue. I have given vastly more to humanitarian causes," said the Tesla CEO.

He added that he thinks humanitarian issues are extremely important both to himself and to everyone.

Climate change "affects every living creature on Earth," Musk tweeted in one of several posts Saturday.
