Members of the Trump campaign’s legal team have made a series of claims about Dominion Voting Systems and alleged ties to Venezuela in their attempt to cast doubt on the presidential election results.

In a press conference on Thursday, Rudy Giuliani claimed that “many” ballots are calculated overseas and open to hacking as he introduced lawyer Sidney Powell, who attempted to tie Dominion Voting Systems to the Chávez regime in Venezuela.

Many of the claims included errors and overstatements, while others lacked any supporting evidence at all. The press conference was just the latest in an ongoing effort to cast doubt on the results of the November 3 election.

During an interview with Lou Dobbs on Fox News on November 13, Powell claimed voting software from Dominion Voting Systems “was created to produce altered voting results in Venezuela for Hugo Chávez and then shipped internationally to manipulate votes for purchase in other countries including this one.” She also repeated unsubstantiated and debunked claims that Dominion’s voting software altered votes and took votes away from Trump.
