In an interview with USA Today, Secret Service Director Randolph "Tex" Alles said the agency is bumping up against federally mandated salary and overtime caps in executing its mission to protect the president and his family.

USA Today’s Kevin Johnson notes that 42 people in the Trump administration have Secret Service protection, including 18 of the president’s family members. Under President Obama, 31 people had such protection.

“The compensation crunch is so serious that the director has begun discussions with key lawmakers to raise the combined salary and overtime cap for agents, from $160,000 per year to $187,000 for at least the duration of Trump's first term,” Johnson reported.

In a statement, Alles said the agency has the funding it needs for the rest of the fiscal year, which runs through Sept. 30, but estimated that 1,100 employees run into statutory pay caps as a result of overtime work during this calendar year.

“This issue is not one that can be attributed to the current Administration’s protection requirements alone, but rather has been an ongoing issue for nearly a decade due to an overall increase in operational tempo," Alles said in the statement.
