GOP nominee Donald Trump has charged that Democrats are making up polls as a way of "suppressing" his campaign.

"Major story that the Dems are making up phony polls in order to suppress the Trump. We are going to WIN!" Trump tweeted Monday morning.

Trump is most likely referring to the fact that in a plethora of recent polls, outlets such as Reuters, The Washington Post and ABC News have been disproportionately polling more registered Democrats, and presenting the findings as a fair representation of all voters.

Some of the polls have shown Hillary Clinton to be leading by double figures.
