Solo has long been a lightning rod for controversy.
She still faces a possible trial on misdemeanor domestic violence charges after a 2014 incident at her sister's home in which she was accused of being intoxicated and assaulting her sister and 17-year-old nephew. Solo said she was a victim in the fight. Earlier this year, an appeals court in Washington state rejected Solo's request to avoid trial.
She was suspended for 30 days early in 2015 for her conduct.
In early 2015, while Solo was at a team training camp in Southern California, her husband, Stevens, was arrested on suspicion of driving under the influence in a U.S. Soccer team van. Solo was with him at the time.
U.S. Soccer said in its statement announcing her suspension on Wednesday that it was a culmination of events.
At the same time, Solo has been stellar on the field.
She became the first goalkeeper with 100 international shutouts last month when the United States defeated South Africa 1-0 at Soldier Field in Chicago. It was also her 150th career win.
