The legal team of US President Donald Trump has filed a lawsuit to challenge the presidential election results in Wisconsin in the state’s Supreme Court.

The latest suit will seek to challenge the results based on allegations of four counts of voting procedure violations. The Trump team’s claim mostly focuses on calling out violations in mail-in voting, which the president has long accused of being prone to fraud.

“Today’s suit includes four cases with clear evidence of unlawfulness, such as illegally altering absentee ballot envelopes, counting ballots that had no required application, overlooking unlawful claims of indefinite confinement, and holding illegal voting events called Democracy in the Park”, a statement by the Trump campaign read.

The new round in Trump’s legal battle over the election results and alleged violations and voter fraud comes a day after Wisconsin’s Democratic Governor Tony Evers certified the results of the counting, citing his “duty” to do so. The governor stressed that state election officials had ensured that Wisconsin had “a safe, fair and efficient election”.

Evers announced his decision on November 30 after state election authorities finished recounts in two counties – Milwaukee and Dane – which failed to tip the scales in favor of incumbent President Donald Trump, who had requested them. Several other states where Trump is disputing the results, namely Arizona, Nevada, Michigan, and Pennsylvania, have already certified the voting results, while Wisconsin has become the last battleground state to do so.
