The White House is backing away from President Donald Trump’s promise to launch an investigation into the voter fraud claims he made up.

One senior administration official told CNN that while such an investigation could happen in the future, it was no longer a priority. This explains why the executive order on the probe that White House Press Secretary Sean Spicer said Trump would sign last month was never released.

The president said that the investigation would target undocumented immigrants, dead people who were still registered and those registered to vote in more than one state.

I will be asking for a major investigation into VOTER FRAUD, including those registered to vote in two states, those who are illegal and.... — Donald J. Trump (@realDonaldTrump) January 25, 2017

even, those registered to vote who are dead (and many for a long time). Depending on results, we will strengthen up voting procedures! — Donald J. Trump (@realDonaldTrump) January 25, 2017

His rhetoric echoes remarks he made during the campaign that the election process was “rigged” against him.

Despite Trump’s repeated efforts to cast doubt on the validity of the election, Americans aren’t convinced. A Politico/Morning Consult poll released earlier this week found that only 1 in 4 respondents believed his claims.
