Donald Trump and his Republican allies are ratcheting up baseless claims that the Nov. 5 U.S. presidential election could be skewed by widespread voting by non-citizens in a series of lawsuits that democracy advocates say are meant to sow distrust.

The House is expected to vote this week on legislation that would mandate proof of citizenship to register to vote.

A new poll has revealed that seven in 10 Americans are concerned that officials will not accept the results of the upcoming elections, with half of respondents expressing concern about potential voter fraud and non-citizen voting.

When Republicans vote on Wednesday to tie a stopgap spending bill to requirements for voters to prove citizenship they will have the backing of Americans, according to a new poll for DailyMail.com.
