It was not the only incident that led to the penalty, Ellis said in her first public comments since the suspension was announced.
"Over time, there's been off-the-field distractions and the federation has taken action," Ellis said in comments released by U.S. Soccer.
"Each time action has been taken, there’s been made clear an expectation that this would be the last time such a step would be necessary.
"It wasn’t a decision just made about comments, it was a sum total of actions that have unfortunately shone a negative light on our program."
Solo, 35, was previously suspended for 30 days in early 2015 for her conduct after a domestic violence case that was dismissed after she pleaded not guilty to striking her sister and nephew during a dispute at her home in the Seattle suburb of Kirkland.
