Trump’s campaign volunteers braved the snow-covered roads Saturday to come to his Iowa headquarters in Urbandale and help the former president make his final push to turn out supporters.

Arizona Republican Senate candidate Kari Lake made an appearance and mingled with volunteers at Trump’s campaign headquarters here, where they phoned potential caucusgoers and volunteers assembled yard signs.

“My free time is Trump time,” said Mara Brown, a Trump campaign volunteer from Urbandale who is in her 60s.

Trump focused on logistics during a tele-rally call with supporters Friday night, as his campaign moved in-person events into virtual events to accommodate the weather.

"I know it’s gonna be very cold, but I know you know how to handle the cold better than anybody," Trump said. "And the caucus locations are all indoors and any lines are going to move very quickly."

"We're looking to set records, and we think that frankly, the other teams aren't going to be as persistent in getting out as our team," Trump said.

Ramaswamy kicked off another day of Iowa campaigning in Spencer, where he called on Iowans to caucus for him despite noting, “If I weren’t in this race, I couldn’t imagine caucusing for anybody else other than Donald Trump.”

While Ramaswamy praised Trump, he also addressed points of contrast with him, at one point saying he was a part of the establishment. "The likes of John Bolton and Nikki Haley will not be my vice president and will not come anywhere near my administration," Ramaswamy said.

Michigan Republican Party Chair Kristina Karamo said Saturday that she received a vote of confidence to remain in her position amid an effort to oust her, but it's unclear who voted and what the next steps in the fight will be.

NBC News' Allan Smith and Henry J. Gomez reported on the situation yesterday:

"A large group of Michigan state GOP committee members voted last week to remove Kristina Karamo as chairwoman, asserting that she was leading the party toward bankruptcy and failing to live up to promises of transparency and reform. The party’s No. 2 official then declared herself acting chair. Karamo rejected the vote, arguing that the process was illegitimate and a violation of state party bylaws. Karamo has called her own meeting for Saturday."

Campaigning in Cedar Falls, Iowa, this morning wearing a shirt that says "she who dares wins," Haley made an impassioned plea to her audience to "make history" on Monday — but not just by voting for a woman, she said.

"And I'm not talking about history of a female president," Haley said. "I'm talking about history saying we are going to finally right the ship in America. We're finally going to get it right."

Haley made only a brief mention of her competitors and not by name — just saying, "The fellas are scared."

DeSantis explained to reporters outside one of his events why he's planning to travel first to South Carolina after Monday's caucuses instead of going straight to New Hampshire, the next primary state.

"We’re going to do an event in Greenville in the morning and then fly to New Hampshire that same day and do a televised town hall with CNN," DeSantis said, adding that he thinks Haley and Trump have weakness in the state.

"We have 74 endorsements from current and former state legislators. She’s got 14. I have way more than Donald Trump does as well. And so it’s like, wait a minute, she was governor for six years, and yet most of them side with me because they see me as representing the values of South Carolina," DeSantis said.

South Carolina's Republican primary is Feb. 24, just over a month after New Hampshire's Jan. 23 contest.

At his first stop of the day in Council Bluffs, Iowa, DeSantis promised to fight for Iowans if they fight the elements for him on Monday night.

Outside DeSantis' super PAC-sponsored event, the wind chill dropped to an arctic 30 degrees below zero, but DeSantis promised to press on campaigning: “I am not going to be canceling — if people are willing to come out and hear from me, I’m going to show up all the way until the end of this caucus,” he said.

“If you’re willing to go out there and you’re willing to brave the elements on a cold, windy, snowy January night for me and do that for a few hours, I’ll fight for you for the next eight years,” DeSantis told the crowd of about 70 at an event space in a residential neighborhood in Council Bluffs.

Haley’s campaign announced Rep. Ralph Norman, R-S.C., will campaign for her in Iowa ahead of Monday’s caucuses.

“Whether it’s taking on the big-spending establishment or defending the sanctity of human life, Nikki has always fought on the front lines of the important conservative battles,” Norman said in a campaign announcement. “I’m excited to come to Iowa and help her win every vote leading up to caucus day.”

Norman is Haley’s only congressional endorser. Trump has vacuumed up far more support than others from the House and Senate — and he is the only GOP presidential candidate to receive any congressional endorsements since June, according to NBC News' analysis.

DeSantis has been campaigning in recent days with GOP Reps. Chip Roy and Thomas Massie, two of his five congressional endorsers.

DeSantis took advantage of yesterday's snow day to relax at the end of Friday with some of his closest advisers and friends, ahead of a final blitz of campaigning this weekend.

The Florida governor — joined by his wife, Casey, senior campaign staff, donors, volunteers and friends — gathered for a casual celebration at Bevy’s Tavern in the Des Moines suburbs to thank team members for their efforts before Monday night’s caucuses.

With just two days left until Iowans make their presidential preferences known, the governor has made nearly 170 stops across the state, with four more stops on his campaign schedule today. DeSantis will start his day today in the western reaches of the state, making stops in Council Bluffs and Atlantic, followed by a drop-in at the super PAC Never Back Down’s headquarters in West Des Moines. He’ll end the day with a town hall in Davenport, on the border with Illinois.
