AUGUSTA, Maine (AP) — The latest federal campaign finance reports show U.S. Sen. Angus King is the top fundraiser in the 2018 U.S. Senate race.

King reported raising about $650,000 during the spring and nearly $1.6 million in total this year.

He received $20,000 apiece from aerospace and defense corporation General Dynamics and leadership PACs led by Democratic U.S. Sens. Elizabeth Warren and Chuck Schumer.

Republican state Sen. Eric Brakey is mounting a run against King, an independent and former Maine governor.

Brakey reported raising nearly $80,000 during the spring and having about $32,000 on hand. Brakey received $1,000 from the National Cannabis Industry Association PAC and $5,000 from Republican U.S. Sen. Rand Paul’s leadership political action committee.

Republican Gov. Paul LePage this week again said he might run against King.

State Sen. Eric Brakey, R-Auburn, is challenging U.S. Sen. Angus King, I-Maine, in 2018.
