Even after the settlement, rejections of midwife-issued birth certificates continued. In 2012, CNN wrote an article about the phenomenon; in 2014, NPR program Morning Edition ran a segment. Both articles quote Jaime Diez, a lawyer also quoted heavily in the Washington Post piece. They also include accounts of people having their passports taken from them as they tried to enter the US, being harassed by Border Patrol agents, and being forced to agree to their own deportation.

What’s changed under Trump appears to be mostly the scope of the denials: according to the attorneys the Post spoke to, at least, there’s been a “surge” in new denials, as well as of people being actually put into deportation proceedings (something that Immigration and Customs Enforcement officials can choose to do when a passport is denied for absence of evidence of US birth, but don’t have to do).

Additionally, the government appears to have expanded its “suspicions” not just to birth certificates signed by midwives, but those signed by longtime South Texas obstetrician Jorge Treviño — who delivered thousands of babies, often in home births, before his death in 2015. (One lawyer told the Post that the government has an affidavit from an anonymous Mexican doctor alleging that Treviño falsified a birth certificate; Treviño, being dead, can’t answer the allegations.)

But perhaps most importantly, this is happening under President Donald Trump, who hasn’t exactly built up a record of goodwill among immigrants, US-born Latinos, or white liberals. And so the report has raised concerns not only about the harassment facing the particular passport applicants in South Texas, but about how broadly the Trump administration could challenge the citizenship — and voting rights — of other groups as well.

My bolding.

Maybe revoking passports isn't exactly the same as revoking citizenship, but being denied the right to travel internationally makes people's lives difficult, especially when they have no recourse.
