A woman accused of being a Russian spy who attempted to infiltrate US political organizations has been moved to the same Virginia prison as Paul Manafort, the President's former campaign manager.

Maria Butina, 29, was indicted last month on several counts including charges of conspiracy to act and failing to register as an agent of a foreign government, according to The Washington Post.

She has pleaded not guilty to all charges.

Butina was transferred from a Washington DC jail to a new holding facility in Alexandria, Virginia, this week, her attorney Robert Driscoll confirmed to the Post on Saturday.

It remains unclear why she was moved to a new jail.

'As a matter of policy, we do not disclose information related to individual prisoners to protect their privacy, safety and security,' a spokesperson for the US Marshal Service said.

Driscoll said the transfer occurred at around 5pm on Friday. The jail in Alexandria is the same facility where Paul Manafort is currently being held while he awaits a verdict on his trial for tax evasion and bank fraud.

The trial now underway in Alexandria, Virginia, is the first case brought by special counsel Robert Mueller to go to trial. The jury will return Monday to begin a third day of deliberations on 18 counts.

As jurors weigh Manafort's fate in the sprawling financial fraud case, the former Trump campaign chairman still has another trial looming in the nation's capital.

In the District of Columbia, Manafort is scheduled to go on trial in September on charges including conspiracy to defraud the United States, failing to register as a foreign agent, money laundering, witness tampering and making false statements.

The transfer occurred just days after the Russian Embassy in Washington DC complained about Butina's jail conditions and claimed that her 'health has deteriorated.'

'It seems as if Washington is trying to force her to cooperate with the investigation by making her living conditions as difficult as possible,' the embassy tweeted on Thursday, adding a 'FreeMariaButina' hashtag at the end.

Driscoll said he was unsure whether the transfer was related to the embassy's concerns.

The Justice Department accuses Butina of being directed by a 'high-level' official in Russia to infiltrate the National Rifle Association and build relationships with conservative politicians from 2015 to 2017.

Russia's foreign minister told the U.S. Secretary of State on last month that Butina had been detained on 'fabricated charges' and should be released.

Butina worked for Alexander Torshin, a Russian banker with close ties to the Kremlin, and served as his interpreter at various Washington events.

The investigation into Butina’s efforts to influence American politics was overseen by the Justice Department’s National Security Division and the U.S. Attorney’s Office for the District of Columbia, and not by Mueller’s office.

Democrats on the U.S. House Intelligence Committee investigating any ties between Trump’s campaign and Russia previously highlighted Butina as a person of interest and sought permission from the committee’s Republican leadership to bring her in for questioning.

Republicans declined that request and later issued a report along party lines that found there was no collusion between Trump’s campaign and Russia.
