The DOJ also said in its filing that Butina and US Person 1 took steps "consistent with a plan to leave" Washington, DC, in the days leading up to her arrest last weekend.
Butina used a United States citizen, who isn't named by prosecutors but matches the description of political operative Paul Erickson, to gain access to an extensive network of Americans in position to influence political activities in the country, prosecutors said.
Prior to her arrest, "we have been offering to cooperate with the government the entire time and have been met with silence", Driscoll said.
Prosecutor Erik Kenerson told the court that "the evidence is overwhelming the defendant was here on behalf of the government of Russia.to carry out a covert influence campaign".
The document says that when Butina lived with her older boyfriend, she allegedly offered to engage in a "honeypot" scheme, which is using sex to either trap, blackmail, or obtain intel from a target.
In a new court filing, the Federal Bureau of Investigation alleges that Butina during her time in the United States cohabitated with an unidentified 56-year-old man as part of her cover while conducting her work in the United States.
"Because Butina has been exposed as an illegal agent of Russian Federation, there is the grave risk that she will appeal to those within that government with whom she conspired to aid her escape from the United States", the government's attorneys wrote.
In Russia, she is known as a fervent gun rights activist with ties to Alexander Torshin, a senior official with Russia's central bank and a former lawmaker.
Ahead of an afternoon court hearing in Washington, the government released documents arguing that Butina constituted a flight risk, citing among other factors, her recent "intention to move money outside of the United States" and indications that she was preparing to move out of her residence, as well as her alleged "ties to the Russian Intelligence Services" and other Russian billionaires.

In October 2016, "U.S. Person 1" told Butina in an email that he had "been involved in securing a VERY private line of communication between the Kremlin and key "Political Party 1" leaders through, of all conduits, the "Gun Rights Organization.'" Helson concluded that this email showed the American's "involvement in Butina's efforts to establish a 'back channel" communication for representatives of the Government of Russian Federation".
The 29-year-old is alleged to have been in contact with Russian intelligence officials and spoke to wealthy Russian oligarchs to fund her trip to America, according to the Federal Bureau of Investigation.
"The concern that Butina poses a risk of flight is only heightened due to her connection to suspected Russian intelligence operatives", prosecutors wrote.
She added that the Russian Consul in USA was attempting to get access to Butina. She is also accused of trying to establish back-channel lines of communications for the Kremlin.
"On at least one occasion, Butina offered an individual other than U.S. Person 1 sex in exchange for a position within a special-interest organisation", prosecutors said. "What can I say!" Butina had been living in Washington since 2016, after coming to the USA on a student visa to study at American University.

AP Erickson first invited scrutiny past year, when The New York Times reported that he emailed Trump campaign aide Rick Dearborn in May 2016, with the subject line "Kremlin Connection", telling him that he could arrange a backdoor meeting between Trump and Russian President Vladimir Putin. Law enforcement officials then became concerned that Butina appeared to be planning to leave the Washington area and made a decision to seek charges and make an arrest, according to people familiar with the case.
