Donald Trump keeps spreading claims that the presidential election is "rigged" against him.

Trailing rival Hillary Clinton in recent polls after a brutal week, Trump took to Twitter over the weekend to blame the electoral process and media.

Tweet: The election is absolutely being rigged by the dishonest and distorted media pushing Crooked Hillary - but also at many polling places - SAD

He also focused on several sexual assault allegations published in recent days, which he has vehemently denied.

Amid his troubles, Trump tried to sow doubt in the integrity of the election, pushing unproven statements that the media is publishing negative stories about him to ensure Clinton is elected.

Tweet: 100% fabricated and made-up charges, pushed strongly by the media and the Clinton Campaign, may poison the minds of the American Voter. FIX!

Tweet: This election is being rigged by the media pushing false and unsubstantiated charges, and outright lies, in order to elect Crooked Hillary!

Trump's recent troubles stem from a 2005 video leaked last week that show him bragging about groping women without consent. Following the tape's release, several Republican lawmakers said they would no longer support Trump. Multiple women also claimed Trump sexually assaulted them years ago.

Clinton leads Trump by 11 points, according to a national NBC News/Wall Street Journal poll released Sunday.

Amid his struggles, Trump has taken to complaining about unfair treatment, at campaign rallies and on Twitter.

In a statement, Clinton's campaign called Trump's comments "shameful attempts to undermine an election weeks before it happens," saying voter participation should not be "undermined."
