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

Sen. Ron JohnsonRonald (Ron) Harold JohnsonLindsey Graham basks in the impeachment spotlight Sunday shows — New impeachment phase dominates Rand Paul says Trump has 'every right' to withhold Ukraine aid over corruption 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 NielsenFive things to watch at Supreme Court's DACA hearings This week: House kicks off public phase of impeachment inquiry Senators urge Trump to fill vacancies at DHS 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.”
