White House press secretary Robert Gibbs said on Twitter Friday afternoon that Susan Collins, the Republican junior senator from Maine, will support Elena Kagan to suceed retired Justice John Paul Stevens.

Collins had announced her support a few minutes earlier in a statement.

She will be the third Republican committed to supporting Kagan in her final confirmation vote. Sens. Lindsey Graham (R-S.C.) and Richard Lugar (R-Ind.) backed the presumptive Supreme Court justice on Tuesday and Thursday.  

Gibbs tweeted:
