Dutch lawyer Alex van der Zwaan was sentenced to 30 days in prison and $20,000 in fines Tuesday. This comes after van der Zwaan pleaded guilty in February to lying to FBI agents about his communications with deputy Trump campaign manager Rick Gates and an unidentified individual, labeled "Person A" in court documents, who is believed to have ties to Russian intelligence.

Why it matters: The decision marks the the first sentencing in Special Counsel Robert Mueller's investigation.
