evidence: President Joe Biden visited the US-Mexico border on Sunday for the first time as president, but he did not appear to see or meet with migrants, including during a trip to a migrant respite center. Biden spent several hours in El Paso in his first visit to the southern border as president, following growing outcry and criticism that he had not yet seen the crisis created by the record number of migrants trekking to the border first hand. But that brief visit appeared largely focused on enforcement issues and speaking with border enforcement personnel. Reporters on the ground did not see any migrants at the respite center during the president’s visit there, nor along the motorcade routes throughout the afternoon. [...] The president’s flight was met by Texas Gov. Greg Abbott, a persistent critic of Biden and his administration for the federal response to migration on the US southern border. The Republican governor confirmed to reporters that he gave Biden a letter outlining what he described as "chaos" on the border.
