STORY HIGHLIGHTS

(CNN) -- The Republican 2016 presidential field is starting to come into focus with potential contenders making notable moves this week.

Here's a breakdown of the latest headlines starting to shape the early race for the Republican nomination.

Portman is out

Pollsters can cross one name off their long list: Rob Portman. The Ohio Republican announced Tuesday he's running for re-election to his Senate seat.

Portman was vetted, but ultimately not picked, to be Mitt Romney's running mate in 2012, and he would have been the first pro-same sex marriage Republican presidential candidate if he ran this cycle.

He said as recently as two weeks ago that he was considering a presidential run, telling CNN's Erin McPike that he "probably (has) more experience than other people who are running or thinking about running."

Instead the senator will seek a second term in the Senate, where he thinks he can "play the most constructive role."

Bush is "thinking"

Jeb Bush reiterated that he's still considering a presidential run, revealing more details Monday about his decision-making process.
