The United States Conference of Mayors, including Austin Mayor Adler and several Austin City Council members, gathered In Tornillo, Texas June 21 to visit an immigrant shelter at the Texas border.
De Blasio said border agents approved the crossing after his security detail asked to venture into Mexico so the mayor and other elected officials could get a different view of facility holding youths.
Agents with the Weslaco Station saw a group of people who had previously been unable to enter the US climbing a tree to enter the country through Custom and Border Protection's (CBP) Port of Entry in Progreso, the agency said in a Wednesday news release.
According to the letter, a uniformed Border Patrol agent noticed a group on the Rio Grande River flood plain south of the Tornillo, Texas, Port of Entry, taking photos of the holding facility.
A New York Police Department inspector reportedly responded that they had not and that they reached the location by coming from Mexico. But the group disregarded the order, walking back to their vehicles and driving back to Mexico, according to the letter.

He also said he thought spending of 4 percent on defence - similar to the USA level - would be the right level. Trump's comments came in a wide-ranging news conference after attending a special meeting on defense spending.
During Austin Mayor Steve Adler's visit to the border at the height of President Donald Trump's "zero tolerance" immigration policy, Adler reportedly illegally crossed the border, according to a report from Fox News.
"It's happening right here, in our name, with our taxpayer dollars, and we got to stop it right away and if the federal government won't answer it, I really do think it's up to all of us, city by city to find any solution we can to reunify these families", de Blasio told Maddow.
"The mayor crossed the border with the direct approval and under the supervision of the border patrol supervisor at this port of entry", Phillips said. However, CBP alleges de Blasio's group left and went back into Mexico. "Any suggestion otherwise is a flat-out lie and an obvious attempt by someone to attack the Mayor because of his advocacy for families being ripped apart at the border by the Trump Administration". ICE is not reasonable law enforcement.
A spokesman for the Border Protection had no comment.
