President Trump came away empty-handed for now after the longest federal government shutdown in American history failed to pressure Congress into funding his long-promised border wall, purportedly to stop an inflow of drugs and crime from Mexico.

But he is not done making his case on immigration.

On Sunday he rattled off several figures on Twitter about how many undocumented immigrants there are in the United States, how much they cost the country financially and how many had illegally voted in Texas.

There were already many problems with Mr. Trump’s assertion that undocumented immigrants disproportionately bring with them more drugs and crime. And several experts said they had concerns with the figures he disseminated on Sunday.

The White House did not respond to a request for comment.

Noncitizens casting votes in Texas

In one tweet on Sunday, Mr. Trump said that “58,000 non-citizens voted in Texas, with 95,000 non-citizens registered to vote.” He was citing an investigation that Texas officials had publicized days earlier but that Democrats in the state immediately questioned.
