Florida Democratic Senate candidate Patrick Murphy's father recently donated $250,000 to the pro-Murphy super PAC Floridians for a Strong Middle Class, bringing his total contributions to the race to $1.75 million.
The super PAC reported the donations in a quarterly disclosure report filed Saturday night to the Federal Election Commission, the Tampa Bay Times reported.
Multimillionaire Thomas Murphy Jr. donated $1 million to Senate Majority PAC over the summer, and had previously given $500,000 to Floridians for a Strong Middle Class.
Super PACS are prohibited from coordinating campaign efforts with the candidates, but can raise unlimited funds.
Because of the immediate family connection, Murphy's campaign has received flak for his father's donations.
Most recently, a conservative watchdog group alleged elder Murphy's donations demonstrated illegal coordination between Murphy's Senate campaign and the super PACs his father donated to. Former primary competitor Democratic Rep. Alan Grayson made similar accusations earlier this year.
Floridians for the Middle Class ran advertising for Murphy over the summer, but nearly $440,000 of its funds went to Senate Majority PAC. Senate Majority PAC pulled millions of dollars in advertising that it planned advertising for Murphy last month.
Murphy's opponent, Sen. Marco Rubio, maintains a lead in the polls, as a RealClearPolitics average of polls from Oct. 3 through Oct. 13 has him up by 4.7 percentage points.
The Rothenberg & Gonzales Political Report/Roll Call rates the race as Leans Republican.
