Rep. Parker Griffith (R-Ala.) on Monday said he was "confident" he could fill a swath of new vacancies in his office before Congress returns to Washington next week.

Many of the congressman's former advisers, including his chief of staff, announced on Monday they were resigning their posts, in light of their boss' decision last month to become a Republican.

But Griffith stressed in a statement Monday he was sure he could find new people -- this time, those "committed to my conservative principles" -- before the House reconvenes on Jan. 12.

“It is an unfortunate fact that any time a change like this occurs partisanship becomes an issue as it has in this case,” Griffith said in a statement, reported by local media, after wishing his old team well.

“I made the decision to join the Republican Conference because I believe the principles of the Republican Party reflect my own personal convictions,” he added.
