Washington, D.C. ? Republican Fred Thompson on Tuesday reported raising nearly $3.5 million in one month for his expected presidential bid, lagging behind his backers’ original $5 million goal.

The “Law & Order” actor and former Tennessee senator filed documents with the Internal Revenue Service that provided the first glimpse of the all-but-certain White House hopeful’s financial situation.

Thompson spent only $625,745 of the $3.46 million he raised in June, the first month of his preliminary campaign committee, the report showed. Still, the total raised fell short of the $5 million target his backers initially set in a one-month showing for his committee “testing the waters” of a presidential bid.

While he collected more than several other Republicans, including former New York Mayor Rudy Giuliani and Arizona Sen. John McCain, in their initial months as prospective candidates, Thompson’s take doesn’t even compare to former Massachusetts Gov. Mitt Romney’s one-day $6.5 million haul.
