A former chemistry professor will announce Tuesday he will run against California Republican Rep. Ed Royce in 2018.

Phil Janowicz, who taught at California State Fullerton, and now runs an education consulting firm, said, “Our community needs a representative who listens to constituents, opposes the unconstitutional actions of the Trump administration, and defends healthcare for working families.”

Janowicz accuses Royce of voting “in lock-step with Trump 96% of the time,” the Los Angeles Times reported.

“People have become disgusted by the current state of our politics in Washington, D.C. Partisanship and gridlock, never-ending conflict, and promises to ‘drain the swamp’ that are broken as quickly as they are made,” Janowicz said in a statement.

Royce, chairman of the House Foreign Affairs Committee, is among the Republican incumbents targeted by the Democratic Congressional Campaign Committee this cycle. Despite the fact that Royce won re-election last year by 14 points, President Donald Trump lost the district to Hillary Clinton.

But the National Republican Congressional Committee shot back against Janowicz’s candidacy.

“Liberal professor Phil Janowicz may hypothesize he has a snowball’s chance challenging Royce, but in the real world, he’ll find Royce’s support runs deep and wide in Orange County,” he said.
