Only two Democrats broke ranks Thursday to oppose the House resolution that sets ground rules for an impeachment inquiry of President Donald Trump.

Freshman Rep. Jeff Van Drew of New Jersey and 15-term veteran Rep. Collin Peterson of Minnesota complained that the process so far has been overly partisan and is further dividing the country.

The Democratic-controlled House approved the package on a 232-196 vote, with all Republicans against.

Peterson, who represents rural, western Minnesota and is one of the most conservative Democrats in the House, said he has “serious concerns” with how impeachment has proceeded, with a series of closed-door depositions conducted by the House Intelligence Committee and two other committees.

While the resolution includes public hearings and release of transcripts from earlier interviews, Peterson said he was “skeptical that we will have a process that is open, transparent and fair.”

Without support from Senate Republicans, “going down this path is a mistake,” he said.

Van Drew, a dentist and a longtime state legislator, won his southern New Jersey seat last year after it was under Republican control for nearly two decades.
