ANKENY — Democratic presidential candidate Amy Klobuchar gave a speech on a central Iowa Wednesday to highlight what she calls her “heartland economics,” Klobuchar began by talking about this weekend’s mass shootings. She called for passage of universal background checks and a waiting period for gun purchases.

“We have extraordinary power in Washington, D.C., but there’s not been extraordinary courage,” Klobuchar said.

Klobuchar said the so-called “boyfriend loophole” must be closed, too, so stalkers and abusers don’t have access to guns. Klobuchar, a U.S. Senator from Minnesota, said it’s important for “rural voices” to join the call for gun safety measures.

“We need to stand up to lies, we need to stand up for our immigrant community and we need to see change,” Klobuchar said.

Klobuchar noted the Republican congressman who represents Dayton, Ohio has just called for an assault-weapon ban as well as new limits on the amount of ammunition allowed in the magazine or clip that’s attached to a gun. Klobuchar told reporters President Trump has the power to get Republican senators to take action.

“When his party seems to always be ‘How High Can I Jump to Keep You Happy’ as their motto, there is absolutely no way he couldn’t get this done,” Klobuchar said after her speech.

Klobuchar talks with reporters.

For about half an hour, Klobuchar spoke to a crowd at a farmstead near Ankeny about proposals to address ag-related issues, including the end of waivers that let big oil companies escape the requirement to blend ethanol into gasoline.

“I will completely overhaul the refinery waivers, all right? We need transparency,” Klobuchar said, to cheers. “…Memo to the Trump Administration…no one, when this got put in place, thought it would cover Chevron and Exxon.”

Klobuchar promised as president she’d expand federal programs for land conservation and ensure family farmers are the beneficiaries of the federal “safety net” that provides crop insurance subsidies and payments during natural disasters. Klobuchar also pledged to stabilize international trade relationships.

“I can tell you this: I will not be using a meat cleaver — or should I say a ‘tweet cleaver’ — when it comes to our policy on trade,” Klobuchar said.

Klobuchar is one of more than 20 presidential candidates who’ll be campaigning in Iowa this week. She’s embarking on a tour with stops in 20 counties and a visit to the Iowa State Fair.
