While at the ACLU, I also conducted data analysis for litigation and advocacy, and I continue to consult occasionally on data-related issues. Under the Trump Administration, I submitted data-related declarations in cases challenging extreme delays in bringing detained noncitizens before an immigration judge, prolonged detention without a bond hearing, ICE's removal of the bond and release options from its risk classification software, and the Trump Administration's decision to deny asylum seekers bond hearings. I also deposed officials from ICE and the immigration courts to obtain information about immigration enforcement data in our case challenging unaffordable bonds. Most recently, I helped show how rarely the U.S. government had invoked the deportability ground used in Mahmoud Khalil's case.
