Good morning.

A group of 40 House Democrats have described “grave concerns” over the Trump administration’s secretive program of deportation flights and demanded that the Federal Aviation Administration (FAA) address allegations of mistreatment and inhumane conditions on ICE charter jets.

In a letter shared with the Guardian and addressed to the FAA administrator, Bryan Bedford, the lawmakers describe the “urgent need for transparency” over ICE’s expanded use of commercial airliners to transfer detained immigrants and criticise its “inappropriate and dangerous” efforts to conceal these operations.

The letter follows a Guardian investigation that found the administration was transporting immigrants in irregular ways that often violated their constitutional rights.

By how much have deportation flights increased under Donald Trump?…
