The congressman said that Democrats are using calls for impeachment to distract from other issues and raise money.
"They’re desperate for impeachment. They would love to be able to talk about impeachment and immigration between now and the November elections, instead of talking about jobs, and the economy, and health care," he said. "They are desperate to change the dialogue, which is exactly why you heard the president starting to talk about his amnesty cause he’s begging to be impeached."
But Mulvaney urged Republicans to "follow the constitution" and only impeach Obama for "high crimes and misdemeanors."
"Let's not fall into a trap when the guy absolutely wants to be impeached," he said.
