Updated 5:15 p.m. | New Jersey Rep. Rodney Frelinghuysen, the chairman of the Appropriations Committee, announced Monday he will not run for re-election in November.

He is the eighth Republican committee chairman to announce his retirement.

The northern New Jersey congressman, first elected in 1994, was a Democratic target for the first time in years. The 11th District narrowly voted for President Donald Trump in 2016 and even more narrowly for Democratic Gov. Phil Murphy last fall, according to calculations by Decision Desk HQ.

It’s the kind of wealthy, highly-educated suburban seat Democrats are hoping to flip this year.
