JERUSALEM (AP) — To the sounds of his impassioned supporters chanting outside, a defiant Israeli Prime Minister Benjamin Netanyahu strode into a Jerusalem courtroom Sunday to face corruption charges in a long-awaited trial that has overshadowed three inconclusive elections and deeply divided the country.

As he entered the courthouse to become the country’s first sitting prime minister to go on trial, Netanyahu launched into a lengthy tirade against the nation’s justice system in which he accused police, prosecutors, judges and the media of a deep state-type conspiracy aimed to oust him against the will of the people.

“I stand before you with a straight back and head raised high,” he said, surrounded by leading Cabinet ministers of his Likud party. “The objective is to depose a strong, right-wing prime minister, and thus remove the nationalist camp from the leadership of the country for many years.”

The standoff, and Netanyahu’s own fiery rhetoric, looked to worsen the nation’s deep divisions just after Netanyahu swore in what he called a “unity” government with a former rival. Critics have said Netanyahu’s repeated attacks on the legal system risk irreversible damage to citizens’ faith in state institutions.

Outside the courthouse, hundreds of supporters rallied in his defense, packing a narrow street while waving Israeli flags and banners denouncing what they called a corrupt prosecution seeking to topple a leader of historic proportion. Others gathered at his official residence to demonstrate against what they called a “crime minister” and carried posters calling for his resignation. They faced off across police barricades with more of the prime minister’s backers.

Netanyahu faces charges of fraud, breach of trust and accepting bribes in a series of corruption cases stemming from ties to wealthy friends. He is accused of accepting lavish gifts and offering to grant favors to powerful media moguls in exchange for favorable coverage of him and his family. He denies the charges, which come after years of scandals swirling around the family.

Netanyahu entered the Jerusalem courtroom wearing a blue surgical mask, following public health restrictions due to the coronavirus pandemic. He refused to sit until TV cameras left the room, and remained in the front row throughout the session.

During the proceedings, the lawyers and judges also wore masks, with the three-judge panel sitting behind a glass divider. In a hint of what could lie ahead, his lawyer said the defense would need several months to study the hundreds of reams of evidence and to build its legal team.

Netanyahu did not speak during the one-hour session, rising just once to confirm he understood the charges. He will not be required to attend future hearings during a case that legal analysts expect to stretch over several years. The next hearing was scheduled for July 19.

Before the session, Netanyahu said police and prosecutors had conspired “to stitch up” a case against him, and said the evidence was “contaminated” and exaggerated.
