U.S. President Donald Trump said on Monday he was worried that any statements under oath he provides to Special Counsel Robert Mueller could be used to bring perjury charges against him as part of the probe into Russia's electoral interference.

In an interview with Reuters, Trump echoed the concerns of his top lawyer in the probe, Rudy Giuliani, who has warned that any sit-down with Mueller could be a "perjury trap."

The president expressed fears that investigators could compare his statements with that of others who have testified in the probe, such as former FBI Director James Comey, and that any discrepancies could be used against him.
