US health authorities are looking into the death of a three-year-old Venezuelan child who was travelling with her parents from Texas to Chicago on a bus carrying asylum seekers.
A contentious plan has transported thousands of migrants from Texas to Democratic Party-controlled US cities.
The young woman was transferred to a hospital in southern Illinois where doctors on Thursday confirmed her death.
On Friday, Texas officials announced her death but provided no other information.
From the Mexican border city of Brownsville, the bus left. According to Texas officials, passengers were asked about any medical concerns they might have before the plane left the state and their temperature was taken.
The bus “pulled over and security on board called 911” when it was seen that the girl’s condition appeared to be deteriorating, according to officials.
Every person lost, according to representatives of the Texas Division of Emergency Management, “is a tragedy.”
Greg Abbott, the Republican governor of Texas, has used his “Operation Lone Star” policies to send more than 30,000 migrants to Democratic-controlled communities since last year.
The US Department of Justice filed a lawsuit against Mr. Abbott last month for his unwillingness to have a floating barrier on the Rio Grande River removed so that migrants entering the US from Mexico could not do so.
The most recent tragedy occurred a few weeks after an eight-year-old girl lost her life at a Texas border police station.
The second-largest refugee catastrophe in history occurs in Venezuela. Since 2015, more than seven million Venezuelans have left the nation as a result of the political and economic instability.
