I’ve not followed the details, but Menendez was found guilty of corruption and says he will appeal:

Menendez pleaded not guilty to federal charges that he accepted an array of bribes in exchange for helping foreign governments. Jurors deliberated for three days. The conviction on all 16 counts against him exposes Menendez to a sentence of more than 200 years in prison, though such a heavy sentence is unlikely.

The judge scheduled the senator’s sentencing date for Oct. 29.

Menendez condemned the decision in a statement outside the courtroom, so far refusing to resign despite overwhelming calls to do so. His attorneys say they plan to appeal the verdict.

“I am deeply disappointed in the decision,” Menendez said, claiming that he “never violated a public oath,” and that he had “never been a foreign agent.”

The Democrats may force him out, because there is no risk of his seat not staying in Democrat hands:

Shortly after a jury read off the verdict that he was guilty on all counts, Senate Majority Leader Chuck Schumer ended months of resistance and called on Menendez to resign, joining more than half of Senate Democrats who have already done so.

More than a dozen of Menendez’s Senate colleagues had resisted calling for him to step down, with many resolved to allow the New Jerseyan his due process. Now that he’s convicted, even the most reserved Senate Democrats are hardly eager to serve aside a convicted felon, even if it’s only for the remainder of the term.

That’s garbage. They could not care less about “convicted felon.” They care about getting a better and more viable Democrat in there:

If Menendez did step down, New Jersey Gov. Phil Murphy (D), whose wife also briefly ran for Menendez’s seat, would be tasked with appointing a successor. He could appoint Kim [who is already the Democrats’ nominee for the seat; Menendez has been planning to run as an Independent], allowing the congressman to then run as an incumbent, or he could choose another placeholder. In a statement following the verdict, Murphy said he would make “a temporary appointment” for the Senate seat if Menendez’s seat became vacant.

Menendez may try to cling to power, but I think he’s doomed. And that is true even if his appeal were to be ultimately successful.
