WASHINGTON — President Trump said on Wednesday that migrants were “living far better” in Border Patrol detention centers than in their home countries, one day after his own administration reported that children in some facilities were denied hot meals or showers, and that cells were so crowded that migrants begged to be freed.
In a series of posts on Twitter, Mr. Trump criticized Democrats who this week visited Border Patrol facilities in Texas, and reported that migrants had been forced to drink from a toilet. Customs and Border Protection officials have disputed that claim.
“Many of these illegal aliens are living far better now than where they came from, and in far safer conditions,” Mr. Trump said over multiple tweets. “No matter how good things actually look, even if perfect, the Democrat visitors will act shocked & aghast at how terrible things are.”
Mr. Trump’s statements followed weeks of public backlash over allegations about the care of migrants who are held in Border Patrol facilities.
Last month, a team of lawyers who spoke to migrants at a holding center in Clint, Tex., said children did not have access to soap or showers. The Democratic lawmakers said the asylum seekers were kept in cells without running water and slept on concrete.
On Tuesday, the Department of Homeland Security’s inspector general backed some of those findings in a report on conditions in detention centers in the Rio Grande Valley. It warned that overcrowding in the facilities posed an “immediate risk” to Border Patrol agents and migrants, and said some of the asylum seekers had desperately tried to escape.
The report also included images of migrants pressing notes to cell windows pleading for help. One image showed 51 women held in a cell designed for 40 men. Another depicted 71 men held in a cell for 41 women.
“If Illegal Immigrants are unhappy with the conditions in the quickly built or refitted detentions centers, just tell them not to come,” Mr. Trump said in Wednesday’s tweets. “All problems solved!”
A record number of asylum-seeking families, many fleeing persecution, violence or poverty in Central America, have filled facilities along the southwestern border that were built to only briefly hold adults before they were deported.
The Trump administration has tried to deter the immigration surge by raising fees on asylum applications, limiting the daily number of migrants who can apply for asylum at ports of entry and forcing more than 13,000 migrants to return to Mexico to wait for the outcome of their asylum cases.
In April, the administration also tried to deny bond hearings to migrants who illegally entered the United States, which would have kept them in jail until their immigration cases were resolved. The Justice Department’s order was blocked on Tuesday by a federal judge in Seattle.
In a statement on Wednesday, the White House said the Seattle ruling was “at war with the rule of law.”
“The decision only incentivizes smugglers and traffickers, which will lead to the further overwhelming of our immigration system by illegal aliens,” the statement said.
After touring the Clint facility, Democratic lawmakers demanded answers about the migrants’ treatment from Customs and Border Protection, with Representative Alexandria Ocasio-Cortez, Democrat of New York, calling it a “rogue agency.”
“I’m replaying it over and over again in my head,” Representative Madeleine Dean, Democrat of Pennsylvania, who visited federal facilities in Clint and in Homestead, Fla., said in an interview Wednesday. “What in God’s name are we doing there?”
Senator Chuck Schumer, the Democratic leader, also on Wednesday called for the firing of Mark Morgan, the acting commissioner of Customs and Border Protection, who was appointed last week to lead the agency.
Mr. Schumer, Democrat of New York, criticized Customs and Border Protection for the findings in the government report. He also excoriated the agency over a secret Facebook group of former and current Border Patrol agents that featured jokes about migrant deaths and obscene images of members of Congress.
“The horrid conditions C.B.P. has subjected children and families to at the border are nothing short of inhumane and downright inexcusable,” Mr. Schumer said in a statement. “Too much of C.B.P. has been an out-of-control agency for too long, and it must be reined in immediately.”
The House Oversight and Reform Committee has demanded that Mr. Morgan and Kevin K. McAleenan, the acting secretary of homeland security, testify at a hearing next week to discuss the allegations and the Facebook group.
Mr. McAleenan said on Wednesday that the material in the Facebook group was “disturbing & inexcusable.”
“These statements are completely unacceptable,” Mr. McAleenan said in a tweet, adding that an investigation was underway to determine if a Homeland Security official wrote any of the offensive posts.
