With the Iowa caucuses just three weeks away, Bill Clinton is busy rallying support for his wife.
The former president was in the middle of a speech on Thursday when his phone rang.
It was his wife.
"I’ll have to call Hillary back and explain why I couldn’t take it," he said, as the crowd laughed.
Following the call, he continued to speak to the crowd of more than 500.
He went on to criticize Republicans who plan to repeal Obamacare and President Obama’s gun control reforms.
Clinton also praised Hillary as “the best change-maker I ever saw.”
