Thousands of pages of memos written by Supreme Court nominee Elena Kagan shows she has taken positions in the past that lean both left and right.
One memo revealed her arguing that a full ban on partial birth abortion would be unconstitutional.
She wanted exemptions added to allow the procedure in cases of "serious health consequences" for the mother.
The memos also reveal Kagan has stood up for religious freedom. She stood by a California landlord who refused to rent to tenants who were unmarried based on her religious views.
However, Republicans feel that Kagan's documents could have emerged in a more timely manner.
"I remain deeply concerned that Ms. Kagan's records will not be fully produced in time for the committee to conduct a proper review," said Sen. Jeff Sessions of Alabama, the top Republican on the Judiciary Committee. Based on the information senators have so far, he said, "it is clear that Ms. Kagan has demonstrated both strong liberal views and a willingness to substitute those views for sound legal judgment."
