Bernie Sanders, the two-time presidential candidate, is barnstorming Iowa and Nebraska to rally voters against what he calls “the oligarchy” — the kind of high-profile offensive that typically signals a potential run for the White House.

Former Democratic presidential candidate and current U.S. Sen. Bernie Sanders is expected to visit Iowa City on Feb. 22 as part of "Fighting Oligarchy."

Sanders said in a video message that his tour is against billionaires like Elon Musk, who are using power to gain more money.
