BEIJING, April 14 (Xinhua) -- Money politics and clan politics went from bad to worse in the United States in 2015, says a report on the U.S. human rights record, issued by the State Council Information Office on Thursday.

Corporations and individuals were able to donate an unlimited size to super Political Action Committees (super PACs) to influence the presidential election, according to the report, which is titled "Human Rights Record of the United States in 2015".

Corporations could use money to sway politics and reap tremendous returns, it says, citing comments that the political system of the U.S. had been subverted to be a tool that provided returns to major political donors.

It says family background had become a primary factor in U.S. politics, with a few families and behind-the-scenes interest groups influencing the election using funds.

According to the report, U.S. citizens' political rights were not effectively safeguarded in the nation where voters found it hard to express their real volition in addition to unfairness in political life due to discrimination against beliefs.

The U.S. citizens' electoral rights were further limited and their right to information was hampered by the government, it adds.
