Michigan Gov. Rick Snyder is sticking by his congressional testimony about when he learned about a fatal outbreak of Legionnaires' disease during the Flint water crisis, despite a senior aide's new disclosure that he informed the governor weeks earlier.

Spokesman Ari Adler says Snyder was "under oath" and "stands by his testimony."

Nearly 100 Legionnaires' cases, including 12 deaths, were reported in the Flint area when the city was using the Flint River for water in 2014-15.
