Severna Park Del. Cathy Vitale contacted the police on Thursday night and said that after Del. Tony McConkey refused to shake her hand at a Republican “Unity” event, he called her names and advanced toward her in an aggressive manner.

McConkey denied the incident took place as Vitale described it, and on Friday called her a “liar.”

According to a report filed with the Anne Arundel County Police Department, Vitale told police the altercation between the two Severna Park delegates took place at 8:53 p.m. at a state GOP-sponsored “Unity Party” held at the Columbian Center in Severna Park.

Vitale said while she was at the function, she saw McConkey and walked over to him to congratulate him on his recent primary election win. Vitale and McConkey, who represent District 33, are two of three Republicans who have advanced to the Nov. 4 general election.

When Vitale extended her hand to shake McConkey’s, she said McConkey began to speak in a raised voice and stepped toward her.

Vitale alleges her husband, Mark Muckelbauer, stepped between the two. Vitale said McConkey then raised his right hand in the air as if to strike her.

Vitale stressed in an email Friday that there was no physical altercation. She did not press charges against McConkey, but “requested the event be documented,” according to the police report.

McConkey said Vitale was the aggressor.

“The woman lies about everything,” McConkey said. “I was standing minding my own business, she thrusted herself into the conversation. She’s trying to fight me and I’m standing there minding my own business.”

Thursday night’s incident comes after McConkey and some of his colleagues had a falling out in 2013.

Sen. Ed Reilly, R-Crofton, filed an ethics complaint against McConkey.

The complaint led to an investigation by the General Assembly’s ethics committee finding McConkey failed to disclose a conflict of interest and improperly pushed for legislation that committee said would have made it easier for him to regain his suspended real estate license.

Neither Vitale nor the other five competitors in District 33’s House of Delegates race went after McConkey for the ethics issue during the campaign.

But Reilly, who ran uncontested to retain his Senate seat and formed a slate earlier this year with Vitale, sent out a letter to 10,000 Republican voters in the area asking them not to vote for McConkey.

Reilly’s letter, which he said Vitale had no role in creating or distributing, listed events that have occurred during McConkey’s three terms in office, including the reprimand.

“It is my request that you research these activities and ask yourself if he should be returned to public office,” the letter said.

McConkey, Vitale and Crofton’s Sid Saab were picked by voters to advance to the Nov. 4 general election.

Vitale told police that it wasn’t the first time she and McConkey disagreed.

“Vitale advised that she and McConkey have had their differences in the past, but McConkey has never been so aggressive or angry prior to this occasion,” the report says.

After Muckelbauer stepped between McConkey and Vitale on Thursday night, the police report says the confrontation ended when Wes Adams, the Republican nominee for Anne Arundel County State’s Attorney, intervened.

Adams declined to comment Friday on what happened before he stepped in.

“All I did was step in like people would. Mark backed away and that was it. I have no comment on any of the rest of it,” Adams said. “Things get heated between people and I didn’t see any other parts of it. What I saw I’m not commenting on. I just happened to be the guy who was there.”

McConkey said he would not file his own police report in response to Vitale’s report.

“The fact that she had to run and file a police report,” McConkey said, “obviously shows she feels guilty about something.”

Thursday’s “Unity Party” was intended to bring the party together after heated races leading up to the June 24 primary election.

The event featured a speech by Larry Hogan, the Republican nominee in the governor’s race.

There was also a friendly hug between current Anne Arundel County Executive Laura Neuman and Del. Steve Schuh. Schuh defeated Neuman in the primary election, earning his party’s nomination over the incumbent.
