Republican Lombardo sworn in as Nevada governor

Former Clark County Sheriff Joe Lombardo has become Nevada's 31st governor.

He took office Monday on a vow to raise criminal penalties, diversify the economy and become America's "education governor."

He's promoting vouchers and wants to increase student discipline.

The career police officer-turned-elected sheriff was the only Republican challenger to unseat a Democrat in one of several razor-thin statewide races in Nevada during November's midterms.

His swearing-in took place quickly at the state Capitol. It's a formality, since Monday marks the deadline for his term to start. A more ceremonial event will take place Tuesday.
