House Speaker Paul Ryan, R-Wis., hailed Indiana Gov. Mike Pence Friday as a "steady and secure" running mate for presumptive GOP nominee Donald Trump.

"I can think of no better choice for our vice-presidential candidate," Ryan said following Trump's tweet announcing the pick. "We need someone who is steady and secure in his principles, someone who can cut through the noise and make a compelling case for conservatism. Mike Pence is that man."

Pence served in the House of Representatives alongside Ryan from 2001-13, where he developed an image as a fiscal hawk and of the leading social conservatives in the country.

That reputation slipped during his tenure as governor, after he implemented the Medicaid expansion of Obamacare and agreed to revise a Religious Freedom Restoration Act bill days after signing into law legislation that outraged gay rights activists.

Ryan emphasized the conservative achievements on Pence's record.

"Mike and I have been friends for many years, and he has put his principles into practice by passing the largest state tax cut in the history of Indiana and expanding school choice for Hoosier families," he said. "He will help bring real change to Washington, and so I will do everything I can between now and November to help our ticket and our party win a national majority."

Former House Speaker John Boehner, who also served with Pence but stepped down in 2015, also praised Trump's decision.

"[W]ith his heart, honesty and integrity, he won the trust and respect of everyone with whom he served," Boehner said Friday. "I'll always be grateful for his friendship; his loyalty to the team and the cause during his years in the House; and the relationship we continued to have after the people of Indiana chose him as their governor."
