Federal officials indicated on Thursday that the White House would be withdrawing the nomination of Jeffrey Byard to be head of the Federal Emergency Management Agency after inquiries into his past revealed a possible barroom altercation that troubled Congress and White House officials.

The FBI did not find “substantial” evidence of the incident, but concerns remained after his vetting process was complete. The White House is expected to nominate acting administrator of FEMA Peter T. Gaynor in his place.
