The alleged attack renews cyberwarfare concerns.
Two US congressmen have accused hackers from China of breaking into their computer systems and stealing information on political dissidents, raising concerns at a time of growing global concern about cyberwarfare.
The lawmakers warned that other lawmakers, civilians, and military officials should take steps to protect their laptops and other devices against such break-ins, especially while in China.
The Chinese government has denied any involvement in the cyberattacks.
The two congressmen who made the claims are active in promoting human rights, according to Reuters.
Representative Wolf said that other US government officials had pressured him not to go public with the claims, according to the Associated Press. "My own suspicion is I was targeted by China because of my long history of speaking out about China's abysmal human rights record," said Wolf, according to the report.
Wolf urged congressional hearings on the break-in and wants to raise awareness of the threat of hacking from China and elsewhere, reports Bloomberg.
