Newark Mayor Cory Booker (D) appeared Monday night on MSNBC's The Rachel Maddow Show after describing the negative campaigning by President Barack Obama as "nauseating" the previous day.

Republicans quickly took advantage of the incident, buying online ads to highlight his comments and launching an "I Stand with Cory" petition.

"Anybody who watched the entire Meet the Press, not only was I defending Obama's positions on numerous issues, but I also talked about super PAC money and the negative campaigning and my outrage and really my frustration was about the cynical negative campaigning, the manipulating of the truth," Booker told Maddow. "So here they are plucking sound bites out of that interview, to manipulate them in a cynical manner to use them for their own purposes, and that slogan is really what had me, and basically my entire staff, really fit to be tied."

He said that if Republicans really wanted to stand with him, they could support same sex marriage, women's reproductive rights, affordable health care and lowering the cost of college.

"As far as where my heart is right now I am very upset that I am being used by the GOP this way," Booker continued. "I thought today I was going to be quiet, I've been pushed so far that you are going to hear a lot from me to the extent possible and to the extent that President Obama and his campaign want to hear from me."
