Beto O'Rourke is making good on a promise to campaign heavily in Iowa, returning next week for his second tour of the state in less than a month.

According to his campaign, O'Rourke will spend four days in Iowa beginning Wednesday, and he will travel to at least 10 different counties for nearly two-dozen events.

"We launched this grassroots campaign for president two weeks ago by being on the ground in communities across Iowa, and we're excited to return Wednesday to continue meeting with, listening to and learning from everyone in the state," O'Rourke said in a statement.

The tour will kick off with an event in Ames Wednesday evening. The campaign also has confirmed stops in Carroll, Denison, Sioux City, Storm Lake, Fort Dodge, Marshalltown, Grinnell and Iowa City. O'Rourke plans to spend all day April 6 in the Des Moines metro area.

Unlike many of his competitors, O'Rourke does not have a day job to return to during the week, and he has used his time to set a demanding campaign schedule in Iowa and across the country.

During his first trip to Iowa, which began March 14, the former Texas congressman and Democratic presidential candidate drove himself in a rented minivan to 18 events across 13 Iowa counties.

Afterward, he immediately traveled to New Hampshire and stopped for events in Wisconsin, Michigan, Ohio and Pennsylvania in between. On Saturday, he's holding three campaign launch events in his home state of Texas before heading back to the Hawkeye state Wednesday.

During a recent interview with the Des Moines Register, O'Rourke promised to "do everything I can" to keep up the intensity of his campaigning.

"It’s the only gear that I have," he said. "And I wouldn’t be doing this but for how significant the challenges are that we face and also how promising the opportunity is at this moment. And for Amy and for me and for our family, this is our way to meet this moment and to give it our absolute all and to do it with as many people as we possibly can."

A March Des Moines Register/CNN/Mediacom Iowa Poll showed that 5 percent of likely Democratic caucusgoers prefer O'Rourke as their first choice for president. That's behind former vice president Joe Biden, who has yet to announce a run, Vermont Sen. Bernie Sanders, Massachusetts Sen. Elizabeth Warren and California Sen. Kamala Harris.
