WASHINGTON — Sen. Pat Toomey of Pennsylvania voted Saturday to convict former President Donald Trump of inciting the Jan. 6 insurrection at the Capitol, likely closing the book on a winding and complicated relationship between the two Republicans.

Toomey, who is not seeking reelection when his term ends in 2022, was one of seven Republicans who voted against Trump in his second impeachment trial. The 57 total votes in favor of conviction fell short of the two-thirds, or 67, needed to convict Trump, leading to his second impeachment acquittal.

Every Democrat voted to convict Trump, including Sen. Bob Casey of Pennsylvania.

Toomey, who voted for Trump in both of the former president’s campaigns, had signaled for weeks he was open to a conviction, saying days after the riot that Trump had “committed impeachable offenses.” And he was one of six Republicans who voted to proceed with the trial, rejecting the argument embraced by most of the GOP that it’s unconstitutional to try a former president.

But as a juror hearing evidence, he said little during the trial and hadn’t declared how he planned to vote on the impeachment article itself. He voted against calling witnesses Saturday.

Over the years, Toomey supported the vast majority of Trump’s policies. But he also criticized some of the former president’s most incendiary conduct, and had made clear his anger at the GOP attempt to throw out Pennsylvania’s election results.
