WASHINGTON (CNN) — After the tumultuous few weeks that led up to Paul Ryan taking over as the new House speaker, his first week on the job was a honeymoon from the Republican infighting that sidelined his predecessor, John Boehner. It was productive too.

But there were signs already that the goodwill might not last long for the young speaker who faces many tough choices in the weeks ahead, including how far he is willing to push efforts to defund Planned Parenthood and other conservative priorities and risk a government shutdown.

Ryan shepherded a significant multi-year transportation bill through a rare process that included three days of debate and votes on dozens of amendments on the House floor. Members on both sides of the aisle praised their ability to weigh in on the long overdue bill, the first major rewrite of a highway and infrastructure construction bill in a decade.

The speaker touted his “great week” in his first solo press conference at the Capitol on Thursday, pointing to the bipartisan transportation bill.
