(CNN) – Republican Sen. Pat Toomey of Pennsylvania threw his weight behind Mitt Romney on Tuesday, two weeks ahead of the state's presidential primary.
"I am proud to endorse Governor Mitt Romney as the Republican nominee for president. I am confident Gov. Romney will be a great president and will return our country to the conservative principles that make our nation great," Toomey said in a statement.

The announcement came shortly after former Pennsylvania Sen. Rick Santorum suspended his campaign. The candidate represented Romney's greatest threat in the Keystone State.
"I also congratulate Senator Santorum on a hard fought primary race. He put up a valiant fight and deserves to be commended for his spirited effort," he said.
Elected to the Senate in 2010, Toomey previously served as a three-term U.S. representative for the state and once headed the anti-tax group Club for Growth.
The announcement followed another endorsement from a high-profile Pennsylvania Republican last month. Tom Ridge, former Homeland Security secretary and former governor of the state, also backed Romney.
Toomey will speak before the Republican front-runner at a Chester County dinner Tuesday night in Pennsylvania.
The Keystone State holds is primary on April 24.

So now you want to endorse Romney since Santorum dropped out. This is what I call a fish back. Who's the next fish back? Republicans, Republicans, Republicans & Republicans?
Now that's sad! No wonder Santorum bowed out. Even his own state doesn't like him. Not that Mitt Romney is much better.
Hat a surprise, why didnt he do it a week ago.
Toomey will be retiring in Montco come 2016. Him jumping on the bandwagon won't help, PA hasn't gone repub since 88.
Hey I guest the repubs are gathering around Romney, now there eyes are all set to push fare and lies upon the gullible in society. I wonder how much of us will be left standing when the super rich and they're media empire attack this president from all corners. The problem is, that the people will be the ones defeated. Because when the repubs and rich suck out every penny out of our economy, their will be nothing left to suck up, so they'll take their businesses to China to start their sucking, leaving the American people with nothing.
