Chelsea Manning, the Army private convicted of leaking classified secrets who subsequently underwent a sex change operation, has begun tweeting from prison.

Manning, formerly known as Bradley before her sex change, posted a tweet under a new Twitter account on Friday afternoon and posted a few more comments throughout the day, according to an ABC News report.

Manning was convicted of sending classified information to WikiLeaks, and was sentenced to 35 years in prison in 2013.

Her first tweet said simply “This is my new twitter account =P”. She went on to thank her supporters and talk about life while incarcerated.

She promised to be active on Twitter and tweet at least daily or weekly, but said she didn’t want to tweet just anything. Manning added that she was “hoping to stay connected with this account as much as possible but would rather tweet about more meaningful things than not,” according to the report.

In order to use Twitter from prison, Manning indicated she has to use a voice phone to dictate, quipping “#90sproblems”.

By the time the next morning rolled around, Manning already had 30,000 followers. The report indicates that FitzGibbon Media — Manning is their client — is handling the account, Manning noted in one tweet, “for the time being.”

Manning was convicted under the Espionage Act, as well as other offenses, after he released a massive collection of confidential documents.

Manning said in a statement after sentencing that he had felt female since childhood, and wanted to change her name to Chelsea, expressing a desire to start hormone replacement therapy.

Manning had served as an intelligence analyst beginning in 2009 with an Army unit in 2009, which gave him access to classified databases. The next year, she leaked documents through WikiLeaks and told an acquaintance, who reported her to the Army, resulting in her arrest not long after.

He has the possibility of parole after eight years.
