A series of false and misleading claims have gone viral online days before the US midterm elections.
Some of the claims cast doubt on the legitimacy of the voting process in key states, while others include manipulated content from across the political spectrum.
The BBC has examined some of the most widely shared claims.
False voting machine claims
Claims that voting machines flip votes from Republicans to Democrats and vice versa have dogged US elections for years. Yet to date there is no evidence to suggest that election tampering has taken place.
A handful of posts recently began circulating on social media from voters in Texas who claimed that voting machines were switching their votes from Democrat to Republican. One tweet read: "Texas GOP up to the same dirty tricks."
Local county officials and the secretary of state's office all confirmed receiving a small handful of reports relating to voters experiencing difficulties with touch screen machines, and have encouraged voters to review their ballots before submitting them.
In a local interview, Sam Taylor, a spokesperson for the Texas secretary of state's office, denied any tampering going on and instead put the instances down to user error.
Voting machines have previously been hacked by researchers in controlled studies to test how vulnerable they might be.
Electronic Systems Software, a company which provides voting machines to multiple Texas counties, has acknowledged such controlled studies on their website, but adds that these do not reflect an actual election scenario where "multiple levels of physical and cyber security are always in place".
Texas voting machines are required to go through multiple tests, including one after the election to make sure there were no issues, and locks are placed on the machines to detect possible tampering.
'2,000 mules'
The film "2,000 mules" by right-wing political commentator Dinesh D'Souza claims to reveal widespread voter fraud operating across several swing states in the 2020 election, and has been promoted by multiple Republicans.
On Facebook alone, mentions of the film have had over four million interactions.
One map in the film claims to have used geolocation data to show an individual had visited multiple voting drop boxes in a single day in Georgia. Yet analysis of the map shows that the drop box locations shown in the video do not match up with the same locations on a map.
Evidence from the independent Georgia Bureau of Investigation revealed that in the film coming within as much as 100ft of a drop box was counted as having visited one.
Additionally, some people shown inserting multiple ballots are cited as evidence of voter fraud. One such individual is now suing the film's creators for defamation after a state investigation revealed he was legally depositing ballots for himself and his family members.
