Democratic New Jersey Sen. Cory Booker crossed the border into Juarez, Mexico, to assist asylum seekers in their efforts to reach the United States on Wednesday.

According to a series of tweets from Booker’s press secretary Sabrina Singh, the 2020 presidential candidate crossed the border from Juarez to El Paso in order to “help escort 5 asylum-seekers and try to prevent them from being sent back to Mexico.”

Singh noted that the visit was not made public in order to guarantee the safety of the asylum seekers, adding, “Cory was able to observe the crossing, interactions with federal immigration authorities, and see the disastrous impact of President Trump’s cruel immigration policy.”

Booker’s quiet visit comes just days after a Democratic Congressional delegation visited several migrant detention facilities and reported shocking and horrific conditions to the media.

Democratic New York Rep. Alexandria Ocasio-Cortez, who was part of that delegation, said that officials had directed detained migrants to drink from the toilet — a claim that was refuted by Art del Cueto, vice president of the National Border Patrol Council.
