As a congressman who led the first impeachment of President Trump, Mr. Schiff relished his role in the resistance. Now a senator, he must protect his state’s interests at a perilous time.

Adam Schiff (D-Calif.) said Friday that President Trump invited him and California’s other Democratic senator, Alex Padilla, on a visit to California amid the wildfires ravaging in Los Angeles — an offer Schiff said he turned down only because the Senate is voting on high-profile Trump nominees.

“The senator regrets not being able to join President Trump in Los Angeles due to the Senate vote schedule,” said Edgar Rodriguez. “He welcomes the president’s support for federal disaster aid to assist the thousands of families and businesses impacted by these devastating fires.”
