(USA Today) — Presumptive Republican presidential nominee Mitt Romney, who struggled to gain the support of evangelicals during the primaries, will deliver a commencement address Saturday at Liberty University, one of the largest Christian universities in the country.

The Republican primaries have been effectively over for weeks, but disquiet about Romney among some evangelicals remains, and the speech could allow him to reassure them of his conservative credentials.

Initial backlash from some students at the university prompted the Liberty Champion, the campus newspaper, to editorialize that the commencement speaker does not necessarily have to share their same faith doctrine. Romney is Mormon.
