(CNN) - Ron Paul's campaign confirmed Friday the Republican presidential candidate will launch another online fundraising marathon, or "money bomb," this weekend.
As Paul gears up for the South Carolina primary in one week, his campaign said it hopes to raise at least $1 million in its fundraising push on Saturday and Sunday.

The goal is on par with previous money bombs, which have each raised roughly a million or more.
Contributors are allowed to donate up to the legal maximum of $2,500 to Paul's website, where a real-time tracker displays the amount of money as it comes in, as well as donor names.
His famous fundraising tactic in part helped the Texas congressman take in $13 million in the fourth quarter, far exceeding the $8 million he raised in the previous quarter.
But his numbers pale in comparison to Republican presidential frontrunner Mitt Romney, who reported raising $24 million in the last three months.
An American Research Group poll released Friday showed 20% of likely South Carolina GOP primary voters backing Paul, placing him third behind former Massachusetts Gov. Mitt Romney and former House Speaker Newt Gingrich.
