(CNN) – Sarah Palin's political action committee donated $5,000 to Mitt Romney's presidential campaign on the last day of October, according to filings with the Federal Election Commission.
The amount, while not huge compared to the large donations both candidates have received from individual donors and other committees, is on par with what Palin's group (Sarah PAC) has donated to other Republican candidates running for House and Senate.

For instance, Sarah PAC has given two donations at $5,000 apiece to Rep. Allen's West's re-election bid, and donated a similar pair of $5,000 donations to Ted Cruz, running for U.S. Senate in Texas. Both of those candidates have received strong backing from tea party groups.
The former Alaska governor and 2008 GOP vice presidential candidate said in March she voted for Newt Gingrich in her state's GOP primary. During the hard fought contest between Gingrich, Romney, and former Pennsylvania Sen. Rick Santorum, she chided the eventual nominee for not connecting enough with conservative voters.
"We can't afford to have low voter turnout in the general election, and that is all the more reason for Romney to really start connecting more with conservatives," she told CNN at the Conservative Political Action Conference in February.
In a statement released when Romney chose Rep. Paul Ryan as his running mate, Palin expressed support for the Republican ticket, but didn't expressly use the word "endorse" to describe her feelings toward her party's new standard bearers.
"Congratulations to Mitt Romney on his choice of Congressman Paul Ryan as his running mate," Palin wrote in a statement, which mentioned Romney's name only four times and Ryan's name only three out of over 1,100 words. The statement was posted on her Facebook page.
The donation from Palin's political action committee to Romney's campaign was reported by, among others, The Washington Post.
