(CNN) As President Trump prepares to have a warm welcome for Egyptian leader Abdel Fattah el-Sisi on Tuesday for the second time at the White House, rights groups say they are intensifying their efforts to lobby members of Congress for a less friendly visit.

Egyptian officials are hailing the meeting, which came at the invitation of the US administration, as a high mark for a new era of relations between the two countries.

"President Sisi has been able to restore Egyptian-American relations to their former political and economic prosperity," said Ashraf Osman, an influential member of Egypt's parliament.

The meeting on Tuesday will focus on building the "robust military, economic and counterterrorism cooperation" between Washington and Cairo, the White House said.

But the meeting this week is not without controversy.
