With concern and confusion over how the federal government will respond to disasters this summer, aid groups are readying to expand the ways they help communities after hurricanes, fires and other storms.

(CNN) - The White House plans to withdraw the nomination of Jeff Byard, President Donald Trump's pick to lead the Federal Emergency Management Agency, seven months after he was nominated to the position, a senior administration official and congressional source tell CNN. Instead, Trump is expected to nominate acting FEMA Administrator Peter Gaynor -- who is the agency's confirmed deputy administrator -- for the top disaster relief position, the sources said. Axios first reported the news, and CNN reported earlier Wednesday that Byard's nomination was in trouble. Issues with Byard's confirmation stemmed from a personal issue that surfaced in the last week, and a senior administration official said Byard had notified the White House last Thursday that he wanted his nomination withdrawn. The White House declined to comment.
