The Washington Post’s Glenn Kessler fired off a “fact check” during President Donald Trump’s State of the Union speech, parsing whether migrant women were “sexually abused” or “assaulted” while traveling through Mexico to the United States with human traffickers.

In his remarks, the president appeared to cite a May 2017 report via Doctors Without Borders, which says: “1 in 3 women is sexually assaulted on the long journey north.”

“Tolerance for illegal immigration is not compassionate –it is cruel,” Trump began. “One in three women is sexually assaulted on the long journey north. Smugglers use migrant children as human pawns to exploit our laws and gain access to our country.”

“Human traffickers and sex traffickers take advantage of the wide open areas between our ports of entry to smuggle thousands of young girls and women into the United States and to sell them into prostitution and modern-day slavery,” he continued.

Kessler objected, saying DWB’s survey could be flawed because the organization did not conduct a random-sample survey. Rather, it spoke with 500 women who were treated by doctors — 12 percent who were reportedly women.

Statistic on sexual assault of migrant women is from an unrepresentative sample https://t.co/NT7R5MZVPa — Glenn Kessler (@GlennKesslerWP) February 6, 2019

Fact check: Trump says “1 in 3 women is sexually assaulted on the long journey north.” But there’s less to that number than meets the eye. https://t.co/Rpz00zdH4L — The Washington Post (@washingtonpost) February 6, 2019

The Post’s fact-checker continued: “So the statistic is derived from the experiences of 56 women and cannot necessarily be considered representative of all migrant women.”
