A compilation of that schedule by the Los Angeles Times, reviewed by RealClearPolitics, shows that Harris has not hosted an immigration-specific event since last summer. The last one, a meeting with Asian American, Native Hawaiian, and Pacific Islander leaders in the White House last August, touched briefly on immigration.

White House officials dispute any characterization that Harris’ public schedule tells the whole story. “The vice president continues to lead implementation of the Root Causes Strategy and has been engaging with Cabinet and other Administration officials on this effort,” Harris’ Press Secretary Kirsten Allen told RCP.

Addressing the challenge remains part of the vice president’s policy portfolio. She leads top-level meetings that are not always made public, and she has taken point in diplomatic efforts in the region. For instance, it was Harris who traveled to Honduras for the inauguration of President Xiomara Castro in January. Administration officials hoped to find a new ally in that executive, someone who would help stem the flow of the millions of people heading north through Central America to the southern border. According to an official White House readout, Harris and Castro discussed “a broad range of issues.” Among them migration, but also coronavirus and the economy as well as corruption and gender-based violence.

Despite those efforts, the influx has not slowed, and Biden is expected to end enforcement of Title 42, the pandemic policy that allowed Border Patrol to turn away hundreds of thousands of migrants on public health grounds. Warnings from some Democrats in border states, including Texas Rep. Henry Cuellar, have gone unheeded.
