Senator Kamala Harris, Democrat of California, was cut off by Republican senators on Tuesday as she questioned Attorney General Jeff Sessions during the latest high-profile Senate Intelligence Committee hearing in its investigation into Russian election interference.

Ms. Harris, a former prosecutor, employs a rapid-fire questioning pace more commonly seen in courtrooms — a style that at times has her interrupting witnesses, which is frowned upon in the Senate, where decorum is still prized. But the moments were notable as the second time in a week that Ms. Harris, who is of Indian and Jamaican descent and is the only minority woman on the committee, was interrupted by two male colleagues during a hearing.

Last Wednesday, Ms. Harris was interrupted by Senator Richard M. Burr, Republican of North Carolina and the chairman of the committee, and Senator John McCain, Republican of Arizona, as she tried to question the deputy attorney general, Rod J. Rosenstein. On Tuesday, the two again interjected as she questioned Mr. Sessions over his role as campaign surrogate for President Trump and contact with Russian officials.

“I’m not able to be rushed this fast,” a visibly flustered Mr. Sessions said to Ms. Harris at one point. “It makes me nervous.”
