Senate Homeland Security chairman sounds alarm over 'leadership void' at DHS

Sen. Ron JohnsonRonald (Ron) Harold JohnsonTrump administration floats background check proposal to Senate GOP Republicans wary of US action on Iran Democratic senator warns O'Rourke AR-15 pledge could haunt party for years MORE (R-Wis.) said on Monday that he is concerned about a "leadership void" at the Department of Homeland Security (DHS) amid talks of a shake-up of top staffers.
 
"In addition to congressional dysfunction, I am concerned with a growing leadership void within the department tasked with addressing some of the most significant problems facing the nation," Johnson, the chairman of the Senate Homeland Security and Governmental Affairs Committee, said in a statement on Monday.
 
Johnson's statement comes after Trump announced that Homeland Security Secretary Kirstjen NielsenKirstjen Michele NielsenKirstjen Nielsen drops out of Atlantic Media event after liberal backlash Pence taps former DHS spokeswoman as his new press secretary DHS officials called lawmaker visit to migrant detention facility a 'Hill stunt' MORE would be leaving her post and that Kevin McAleenan, the commissioner of Customs and Border Protection, will lead DHS on an acting basis until a permanent replacement for Nielsen is chosen.
 
In addition to Nielsen, CNN reported that White House adviser Stephen Miller is pushing for Lee Cissna, the director of United States Citizenship and Immigration Services (USCIS), and John Mitnick, the department's general counsel, to be dismissed.
 
A Trump administration official told CNN that there are also questions about the future of Claire Grady, under secretary of management at DHS.
 
 
Grassley noted that Cissna previously worked for him on the Judiciary Committee and is "doing an excellent job leading USCIS."
But the moves signal that Trump is seeking to shake up his team amid frustration over the spike in migrant families crossing the southern border.
 
He yanked his nominee to lead Immigration and Customs Enforcement late last week because he said he wants “to go in a tougher direction.”
