Washington (CNN) - First Lady Michelle Obama is teaming up with Democratic party officials to help fundraise in the final four weeks before the midterm elections.
In an email sent by the Democratic National Committee to members of Organizing for America, the party's grassroots wing, the First Lady says "our organizers and volunteers are knocking on doors every weekend, making calls every night. Your support will help to fund this work."
In the letter, Obama says President Barack Obama can't keep making progress without strong allies in Congress, and she makes a plea to those who worked or volunteered on her husband's presidential campaign.
"If the folks who I saw in 2008 - those of you who packed up your bags and slept on floors and made calls and talked to voters day after day - are ready to stand with us again, then I'm ready for any challenge that lies ahead. That's why we're asking you to help grow this movement once again," says Obama.
The DNC said that the First Lady will also be featured as "a special guest" on a call with Democratic supporters Wednesday.
Michelle Obama is also scheduled to hit the campaign trail starting next week, headlining events for at least nine Democratic candidates and two Democratic committees in the closing weeks of the midterm election.
A recent CNN/Opinion Research Corporation Poll indicated that 62 percent of Americans have a favorable opinion of the First Lady, while only 25 percent have an unfavorable view of her husband. Digging deeper into the survey, 58 percent of independents and 69 percent of women have a favorable opinion of Michelle Obama, making her a valuable asset on the campaign trail.
