Kean, 57, was unopposed in the GOP primary. The Republican’s absence has sparked GOP worry over whether he will hold his seat come November.

Kean’s nomination on June 2 is largely a formality, as he is the only Republican running in the state’s GOP primary.

The pressure is ratcheting up in the 7th Congressional District as Democrats are hoping to unseat Kean in their bid to regain control of Congress.
