Republican presidential candidate urges early Clinton voters to change their ballots in states that allow it.

Republican presidential candidate Donald Trump on Tuesday urged early Hillary Clinton voters suffering from "buyer's remorse" to change their ballots in the few states that allow for it, The Hill reports.

Certain states do allow for absentee voters to change their minds after they cast their ballots. According to the Trump campaign, Wisconsin, Pennsylvania, Michigan and Minnesota are the states that allow such a switch, with varying rules about the process.

"This is a message for any Democratic voters who have already cast their ballots for Hillary Clinton and who are having a bad case of buyer's remorse, in other words you want to change your vote: Wisconsin is one of several states where you can change your early ballot if you think you've made a mistake," Trump said Tuesday night at a rally in Eau Claire, Wisconsin.

"A lot of stuff has come out since you voted. If you live here, or Michigan, or Pennsylvania, or Minnesota, you can change your vote to Donald Trump," he added.

The call from Trump’s campaign followed the re-opening of the FBI probe into Clinton’s private email server.

The agency is reviewing emails related to a separate probe of former congressman Anthony Weiner, who is alleged to have exchanged explicit sexual messages with a 15-year-old girl and is the estranged husband of longtime Clinton aide Huma Abedin.

But it's unclear how many people would follow through on changing their vote, considering early voters are typically more certain about their choice, or either unwilling or unable to wait in line on Election Day, noted The Hill.

Trump’s call came as an ABC/Washington Post poll found that he now has a 1 percentage point edge over Clinton.

The Clinton campaign rejected the poll, claiming it was “bad polling” – even though Democrats touted the same poll last week when it showed Clinton had a 12-point advantage over Trump.
