Monday afternoon, as illegal caravan of an estimated 7,000 Central American migrants are marching their way toward the United States border, President Trump posted a report on Twitter about the cost of “anchor babies” born in the U.S.

The report was originally published by the Washington Examiner on October 9, and began as follows:

Americans are paying more to cover the costs of illegal immigrants having children in the United States than Congress plans to give President Trump in border wall funding this year, according to an explosive new analysis of Census Bureau data.

The new report reveals that women in the United States illegally had 297,000 children in 2014 at a cost of $2.4 billion.

President Trump tweeted, along with the link to the report: “Shock report: US paying more for illegal immigrant births than Trump’s wall.”

In another tweet, the president shared a report that says the United States has the cleanest air in the world.
