Bruce Lee Castor Jr.[1] (born October 24, 1961)[2][3] is an American lawyer and retired Republican politician from Montgomery County, Pennsylvania.

He investigated the Penn State fraternity hazing scandal and led for the defense of the second impeachment trial of Donald Trump along with American lawyer David Schoen.

A week before the election, Andrea Constand, who had accused Cosby of sexual assault in Montgomery County, sued Castor, claiming he defamed her by intimating she was not credible.

[11] In November 2017, Castor sued Constand and her lawyers for defamation, charging that the lawsuit and its timing were retaliatory and ruined his political career.

After two years of time served the Pennsylvania Supreme Court overturned the sentence, ruling that Castor's pledge to not prosecute Cosby was binding on all other prosecutors.

[34][35] When his term as district attorney expired in January 2008, Castor took a position at the litigation firm of Elliott, Greenleaf & Siedzikowski in Blue Bell, Pennsylvania as a shareholder and director.

[36] In 2009, Castor represented Mark Sargent, who was investigated (but not charged) for patronizing a brothel while he served as dean of the Villanova University School of Law.

[38] Marino, a former Montgomery County D.A., was present when the shooting occurred, despite knowing that his nephew was prohibited from owning and using firearms, owing to a felony conviction.

[41] Early in the campaign, Castor commissioned a poll showing that Ellis, who had been hobbled by negative press surrounding alleged domestic violence incidents, would lose in a general election.

However, amid widespread pressure that he would be splitting the party, Castor relented and ran with Matthews against former Democratic Congressman Joe Hoeffel and incumbent commissioner Ruth Damsker in the general election.

A subsequent grand jury report found questionable behavior on Hoeffel's part for his participation in discussing county business at private breakfast meetings held with Matthews and senior aides–an alleged violation of state "sunshine" laws.

Supervisor Leslie Richards, and Castor were elected, marking the first time in county history Democrats controlled two of the three seats on the Board of Commissioners.

All three members of the commission later noted the improved level of civility and functionality on the board, with Castor expressing pride in working with Shapiro and Richards whom he considered "honest.

"[51] The relationship amongst the three commissioners later prompted one columnist of The Philadelphia Inquirer to note that she owed Castor an apology for considering his complaints about the prior county administration "sour grapes".

On January 31, 2021, Castor was appointed to take the lead for Donald J. Trump's defense team for his 2021 impeachment trial, alongside criminal law practitioner David Schoen.

[4] Castor's opening arguments on February 9, 2021, were widely reported to be confusing and rambling,[55][56][57] and famously included the statement "Nebraska, you’re going to hear, is quite a judicial thinking place"[58] that became an online meme.
