(AP Photo/Steve Helber) (Newser) – The Sunday before Super Tuesday saw a wave of headline-grabbing endorsements for both Republican and Democratic presidential candidates. Here's the latest on who's supporting whom: Marco Rubio No. 1: Hobby Lobby CEO David Green said in a statement that he's impressed with the way Rubio "carries himself," KFOR reports. "But most importantly, Marco regularly exhibits humility and gives the glory to God." Green, who lives in Oklahoma, also goes after Donald Trump, saying that his business has "quite possibly" been more successful than the real estate billionaire's, "but that doesn’t make either of us qualified to be president." And Trump's lack of humility "scares me to death." Marco Rubio No. 2: In his endorsement, Tennessee Sen. Lamar Alexander says Rubio is "the conservative candidate who can inspire us, win the election and lead our country," Politico reports. Rubio also has the support of the state's governor, Bill Haslam. Bernie Sanders: Rep. Tulsi Gabbard of Hawaii resigned as vice chair of the DNC so she could support Sanders, NBC News reports. In an email to the DNC, Gabbard, an Iraq veteran, says she "cannot remain neutral and sit on the sidelines any longer," Politico reports, adding that Sanders aligns with her belief that "we must end the interventionist, regime change policies that have cost us so much." It's Sanders' "highest-profile congressional endorsement yet," per Politico. Gabbard is the fourth member of Congress to back Sanders; Hillary Clinton's count stands at more than 150. Donald Trump: Alabama Sen. Jeff Sessions made a surprise visit to a Trump rally in that state and gave the Republican frontrunner his first endorsement from a sitting senator, the Washington Post reports. Politicians have failed to fix illegal immigration, says Sessions, a Tea Party favorite. "Donald Trump will do it. … This isn't a campaign, this is a movement." The endorsement is a "major blow" to Ted Cruz, who has often cited Sessions as an ally, reports Politico.
