Democratic Sen. Bill Nelson said the Trump administration reached a new low by charging detained immigrant parents high fees to call the children they were separated from at the border.

"The Trump administration has been charging detained parents, get this, as much as $8 a minute to call their children," Nelson said July 23 on the Senate floor. "And the children were separated from the parents because the administration separated them; $8 a minute if you want to talk to your child. That is a new low."

We wondered about Nelson's claim that parents in detention were being charged as much as $8 a minute to call their children. Nelson's office pointed to media reports saying parents had to pay for phone calls. But U.S. Immigration and Customs Enforcement rebuked those claims.

About 150 lawmakers, including Nelson, sent a letter July 20 to ICE's acting director, Ronald D. Vitiello, expressing concerns over "apparent misinterpretation" of ICE's telephone access policies.

"Reports and first-hand accounts have indicated that many of these detained parents have been forced to endure weeks without any information as to the location of their children," the letter said. "Once their children are finally located, moreover, reports indicate that their parents are forced to pay as much as $8 per minute to speak with them by telephone, and that their access to this service can be limited to as little as one call per week."

The letter cites a June 21 NPR interview of Jenny Hixon, outreach director for the Refugee and Immigrant Center for Education and Legal Services. Hixon told NPR that some parents at a detention center in Pearsall, Texas, "had not been able to speak to their children yet because in order to be able to speak to their children, they needed to pay $25 to get a commissary account. And then the phone calls are about $8 a minute."

PolitiFact emailed Hixon for more information but received an automated message saying she was no longer employed by the legal services group.

Nelson's office also referred us to a July 3 article from the Texas Tribune reporting that immigrants in detention faced "usurious phone rates and bureaucratic hassles to contact their family members." The story said advocates were worried that "the cost and complexity of using detention facility phones could hamper family reunification efforts that have already been plagued by chaos and confusion."

But the Texas Tribune story didn't cite an $8 a minute rate. It said the cost "can top 20 cents per minute and has been criticized as exorbitant."

The story mentioned comments made in a June 22 court filing by a mother detained in Texas who was separated from her children. "The calls are very expensive so I am only able to call when I have money, but when I do not have money, I am not able to communicate with my children. In one month I only received one free call from the center," the woman said.

The story added: "Lawyers and advocates working with immigrants detained since the 'zero tolerance' policy went into effect say costs and procedures vary from facility to facility, but they have heard that charges range from 10 to 25 cents per minute for domestic calls." It did not say if those calls were made to children.

ICE spokeswoman Jennifer D. Elzea told PolitiFact calls are facilitated "at no charge" to detained parents whether their children are in HHS custody or with sponsors.

But BuzzFeed, in a July 23 story about the lawmakers' letter, reported that "when asked about reports detailing high, per-minute fees for phone calls to children," a different spokeswoman "agreed it was 'possible' that occurred when parents were trying to call children who were no longer in federal custody."

Children in HHS custody don't have 24-hour access to phones, but calls are being arranged at least twice a week, sometimes more frequently, Elzea told PolitiFact. In some cases, detained parents are able to talk to their children through video-conferencing, she said.

ICE detention standards say detainees shall be able to make free calls to an ICE-provided list of free legal service providers, to consular officials and to certain government offices.

"Indigent detainees, who are representing themselves pro se, shall be permitted free calls on an as-needed basis to family or other individuals assisting with the detainee's immigration proceedings," standards say.

HHS said that children in its shelters don't pay for calls to their families or sponsors. The agency said it pays for those calls.

Two legal services groups representing immigrant families were unable to confirm to PolitiFact if parents were charged as much as $8 a minute to call their children.

Some parents detained at Port Isabel detention center in Texas told lawyers that they were charged about $3 a minute to call their children, said Megan McKenna, spokeswoman for Kids in Need of Defense.

"It's possible that there was a free call number, but the detainees our team spoke to did not know about it, if there was," McKenna said.

Efren Olivares, a program director at the Texas Civil Rights Project, said he couldn't confirm the $8 a minute figure. But when detainees at the Port Isabel detention center call Texas Civil Rights Project lawyers, they get a recording saying the call is 20 cents a minute, Olivares said.

Nelson's statement contains an element of truth but ignores critical facts that would give a different impression. We rate it Mostly False.
