The campaign of Republican U.S. Senate candidate Dan Sullivan on Tuesday said it raised over $1 million in the second quarter of this year, putting it close to on par with incumbent Sen. Mark Begich, a Democrat.

Sullivan is one of the three highest-profile GOP candidates in the Aug. 19 primary, along with Mead Treadwell and Joe Miller.

Sullivan's campaign said in an email Tuesday morning it had raised "almost $1.2 million" in the second quarter, which compares to $1.25 million raised by Begich's campaign. Sullivan's spokesman, Mike Anderson, said a precise figure would be available later in the day.

Sullivan's campaign now has $1.7 million in the bank, Anderson said, which is less than the $2.15 million in Begich's account. But Anderson said the gap has narrowed from the end of the last quarter, when Begich had $2.8 million and Sullivan had $1.9 million.

Tuesday is the deadline for Senate candidates to file their second-quarter fundraising reports with the Federal Election Commission. Spokesmen for Miller and Treadwell said Tuesday morning that their fundraising numbers were not immediately available.
