Senate Foreign Relations Committee Chairman Bob Corker will hold a hearing next week on the president's universal authority to use nuclear weapons.
Corker, R-Tenn., has engaged in several public spats with President Trump and has questioned his maturity, at one point calling the White House an "adult day care center" lacking a minder. He has also described Trump as unstable and incompetent.
Corker, who is not running for re-election, said the hearing is part of the Senate's examination of war powers.
The panel on Oct. 30 held a hearing on the congressional authorization of the use of military force, which has not been renewed in 15 years.
Corker said the presidential power to use nuclear weapons has not been examined by Congress in more than four decades.
“A number of members both on and off our committee have raised questions about the authorities of the legislative and executive branches with respect to war making, the use of nuclear weapons, and conducting foreign policy overall,” Corker said in a statement. “This continues a series of hearings to examine those issues and will be the first time since 1976 that this committee or our House counterparts have looked specifically at the authority and process for using U.S. nuclear weapons. This discussion is long overdue, and we look forward to examining this critical issue.”
