SIOUX CITY | Former Secretary of State Hillary Clinton vowed Friday she would do everything in her power to prevent attacks in the United States if she's elected president.
Joined by Labor Secretary Tom Perez at a campaign stop in Sioux City, Clinton also pledged Friday to create jobs and raise incomes through a five-year, $275 billion plan to improve national infrastructure pieces.
Clinton briefly introduced her infrastructure plan to a crowd of 300 at the Local 948 Carpenters Training Center, then pivoted to address Wednesday's shooting in San Bernardino, California, that left 14 dead.
Clinton spoke shortly before the FBI announced it was officially investigating the shooting in a social service center as an act of terrorism. A U.S. law enforcement official reported a woman who helped her husband carry out the attack had pledged allegiance to the Islamic State group and its leader on Facebook under an alias.
"We're learning more, literally, by the hour. There certainly is much more support for the view this was a terrorist act," Clinton said.
Clinton, a former first lady in the 1990s and later a U.S. senator from New York and U.S. Secretary of State, did not specifically mention the Islamic State, which has claimed responsibility for November attacks in Paris that killed more than 100 people. She said U.S. officials must "redouble our efforts to dismantle the structure of global terrorism," in part by sharing more intelligence information with other countries.
"We have to fight them online," Clinton said. "This is the first time we have faced an adversary so sophisticated about using the Internet, using it to recruit vulnerable people, using it even to train, provide information, about planning for attacks. So, we've got to have a strategy to defeat these global terror networks."
Clinton said she supports the U.S. leading international air attacks but said she didn't want U.S. ground troops fighting Mideast terror groups.
"We have to fight them on the ground. That has to be the people there, and not American troops," she said.
Clinton first unveiled her infrastructure plan in Boston on Sunday. The Friday stop in Sioux City marked her first airing of it in Iowa, which holds the first contest in the 2016 presidential selection process with the Feb. 1 caucuses. She said that plan is needed to continue the longest period of private-sector job growth, at 69 months in a row after the monthly jobs report was unveiled Friday, since her husband Bill Clinton was president.
"We are going to create more good-paying jobs for hard-working Americans," Clinton said.
She said her plans would boost airports, sea ports and highways. "The infrastructure is old, it is broken down. My image is, it is held together with duct tape."
Clinton did not detail how she would pay for the five-year plan, but later said she would not raise taxes on the middle class.
Perez joined Clinton in Sioux City to announce his endorsement. "Hillary Clinton is a progressive who gets things done ... Her North Star is the middle class, her North Star is working families," Perez told the audience.
During the event, state Rep. Chris Hall, D-Sioux City, also offered his support for Clinton to be the party's nominee. A national poll from CNN right before Clinton's event showed she had solidified her lead over U.S. Sen. Bernie Sanders, with the largest gap since July. Former Maryland Gov. Martin O'Malley is running third.
Richie Schmidt, a union member from Des Moines who sometimes works in Sioux City, said he decided in the last week to support Clinton. Schmidt didn't caucus for her in 2008, instead giving his support to candidate John Edwards.
Schmidt said Clinton's experience on national issues will pay dividends as president, and he liked the infrastructure proposal shared.
"Her being here sends the message that union workers can work on those projects," Schmidt said.
