US Immigration and Customs Enforcement failed to issue court summons to more than 80% of migrants who crossed into the country illegally under President Biden’s now-defunct “parole” immigrant program, according to a report.

The internal data was revealed by the Washington Times after the government handed over reports to a Florida federal judge.

Just before the end of the Title 42 pandemic-era policy that allowed for the quick removal of apprehended migrants, ICE released the migrants on “parole” and gave them 60 days to check in with its officers, but more than 40% were never heard from, according to the outlet.

Of the remaining 60%, ICE failed to deliver a notice to appear in court in two-thirds of the immigrant cases.

District Judge T. Kent Wetherell said the poor showings illustrated that the parole program was infective and supported his March ruling to block the Biden administration from releasing undocumented immigrants into the US without the court notices.

Thousands of migrants are believed to have been released from Border Control custody under the Biden directive that made it nearly impossible to track them down without a court date.
