President Donald Trump’s latest executive order creates a commission that will study U.S. voting and registration processes, a measure aimed at fighting voter fraud. 

After defeating Hillary Clinton in last year's election in the Electoral College, although the Democrat received some three million more votes than Trump, the president has claimed on several occasions that massive election fraud was committed.

The president declared in January that between three and five million undocumented immigrants voted in the November election and that was the reason that the former secretary of state appeared to have handily won the popular vote.

He said at the time on Twitter that he would call for an investigation into election fraud, including identifying people registered in two states, illegal migrants who may have voted and deceased - but still registered - voters in whose names ballots were cast.

However, there is no evidence that voter fraud occurs on a great scale in the country.

The Presidential Advisory Commission on Election Integrity will be headed by Vice President Mike Pence and is expected to present its conclusive report sometime next year, according to what White House Deputy Press Secretary Sarah Huckabee Sanders said at her daily press briefing on Thursday.

Top Democratic leaders reacted with suspicion to the creation of the commission ostensibly designed to protect the "integrity" of the electoral system.

House Minority Leader Nancy Pelosi said that at times complaints of electoral fraud have been used as a "pretext" to deny voting rights to working families and to certain communities such as African Americans and Hispanics.

Former Democratic presidential candidate Sen. Bernie Sanders said that "The sole purpose of this commission is to propagate a myth and to give encouragement to Republican governors and state legislators to increase voter suppression."
