“Instead of going to Philadelphia tonight and raising money ... why doesn't he call ...[congressioal leadership] into his office and just do his job? Just do his job?" asked Cornyn.

He was one of several senators who criticized Obama Thursday. The president declined the GOP's invite and kept to his scheduled events.

White House officials pointed out that several Republicans are attending fundraising events Thursday, which marks the last day of fundraising for the second quarter. 

The NRSC said that Cornyn’s appearance at an event just blocks from the Capitol building did not equal Obama's travels to Philadelphia.

The senator stands at the ready to work with the president at a moment’s notice, NRSC spokesman Brian Walsh told The Hill. 

“As evidenced by the fact that he made these comments on the Senate floor, it’s clear Senator Cornyn was at work in Washington today and ready to hear the President’s plan to solve our debt crisis,” Walsh said in a statement. 

“Unfortunately, instead of meeting with Senate Republicans, the president felt it was more important to raise campaign cash in Philadelphia,” he added.
