(CNN) - Sen. John Ensign has no intention of resigning his seat and will run for re-election in 2012.
"I fully plan on running for reelection," the Nevada Republican told the Las Vegas Sun Monday. "I'm going to work to earn their respect back."
Ensign, who has admitted to an affair with a former campaign staffer, also told the paper he is receiving calls and e-mails from constituents encouraging him to stay in office, and said Senate leaders "on both sides" have offered their support.
He said he is being told to "(k)eep your head up. This thing will pass."
Ensign has faced mounting pressure following last week's revelation that parents paid the family of his former mistress close to $100,000 after she was no longer working for the senator. A lawyer for Ensign said last week the payments were legally made as "gifts, accepted as gifts and complied with tax rules governing gifts."
In a Mason-Dixon poll conducted shortly after his admission of an affair late last month, only 29 percent of Nevadans said Ensign should step down. The same poll showed Ensign with a 39 percent approval rating, five points higher than that of Nevada's other senator, Democratic leader Harry Reid.
