As press faces rising threats, we double down on journalistic rigor & independence.
“We are convinced that amid our democracies’ struggles—and in spite of them—independent journalists will do their most consequential work”– @MarinaWalkerG

ALT “It’s tempting to feel we have little to celebrate on World Press Freedom Day. Still, as challenges rise, the Pulitzer Center’s partner journalists and outlets are doubling down on rigor, independence, and creativity. The more they are threatened, the busier they get.” - Marina Walker Guevara, Pulitzer Center Executive Editor
Congratulations to @madeleinebaran & @NewYorker team for your so deserved Pulitzer Prize! The @pulitzercenter (no relation to the prizes) is proud to have supported this crucial investigation on the massacre of civilians by US marines in Haditha, Iraq. Onward!

Replying to @_elfaro_ @CarlosDada
@_elfaro_ es un referente de excelencia en el periodismo mundial. Las represalias contra sus periodistas por publicar información de interés público basada en investigaciones y seguimientos periodísticos de larga data generarán un movimiento global de protesta y solidaridad.

"Con una visión maniquea y ultrapersonalista, el presidente de Argentina pasa por encima de los límites institucionales y considera enemigos a quienes piensan distinto o apenas discrepan con sus formas"
Al actuar como actúa, pasando por encima de instituciones y personas, insultando y destratando, Javier Milei olvida que para llegar a un objetivo a menudo resulta esencial el recorrido. Porque sin camino, no se llega al destino.

So, my @pulitzercenter supported investigation on how opaque algorithms declared living people as dead and denied food to the poor in India is featured among
2024’s Best Investigative Stories from India by @gijn . Good to be here third year in a row.

A keeper thread for anyone interested in AI accountability. Congrats @gabriels_geiger 🙌🏽
I do a lot of FOIA and I’m used to stonewalling. But Sweden surprised me. After 3 years of telling me no, a high level official at Sweden’s welfare agency @fk_media accidentally left me on cc, writing “Now we must hope that we are done with him.”

New Suspicion Machines just dropped
Secretive algorithms deployed in Sweden's vaunted welfare system cast suspicion on innocent women & migrants while ignoring men & the affluent. We reveal with @SvD how Sweden built this system then stonewalled journalists

Today Netanyahu's gov't approved a resolution to sanction Haaretz - halting any state advertising, state funded subscriptions or any other "connections" with the paper.
We will not be deterred.
