The article is just a propaganda piece. Other news sources retracted the story to explain that the budget shortfall is due to the chronic shortage of Secret Service agents. The shortage is currently about 1,500. Recall that the Secret Service also provides protection for the four former POTUS and their families. These issues go back nearly a decade. 

In 2015, the Director Pierson was cashiered as were 4 top managers due to rampant incompetence. They seriously underestimated the budget each year. Recall the intruder who ran across the WH lawn, burst through the doors and around the inside of the WH? The sleeping agents on POTUS detail? The shot fired into the WH that wasn't discovered for days? The drone that flew onto the WH compound? The two people who "crashed" a State Dinner with the PM of India?  

Congress allocated additional funds during Obama's Admin due to chronic staffing issues. Just another propaganda piece by DP.
