According to Italian news outlets, the ranking Democrat was reportedly admitted to Umberto I hospital after feeling "slightly unwell" and is undergoing tests.
ABC News reports that the United States Embassy in Rome is aware of reports on Pelosi's condition, but did not comment further. According to the AP, the congresswoman's office in Washington, D.C. repeatedly declined requests to disclose more information on the situation.
NBC News' Luke Russert relayed word on Twitter from Rep. Bill Pascrell (D-N.J.), who's traveling with the Democratic leader, that she's now back at her hotel and "in good shape."
UPDATE: Pelosi spokesman Nadeam Elshami released the following statement on the ranking Democrat's condition:
"After several flights yesterday in Afghanistan, and a long flight back to Italy that arrived early this morning, Leader Pelosi was not feeling well. This morning in Rome, the Leader was advised to visit a clinic, and the closest medical facility was a hospital. The Leader is now resuming her schedule in Italy."
