Elrich said in a statement Saturday his office had not received the letter and only learned about it in news reports. Elrich called the public release of the letter "troubling," saying public discussion of security matters "is counterproductive, and using the media only further draws attention to the security of the Justices' homes and neighborhoods."

Elrich continued, "Quite frankly, discussing security concerns publicly is irresponsible and disappointing behavior."

CNN reached out to the Supreme Court for comment on that.

Michael Ricci, the spokesperson for Hogan, responded in a statement to the letter, saying the governor would direct the Maryland State Police to "further review enforcement options," while noting Maryland's Attorney General has questioned the laws' constitutionality. Ricci also lamented the perceived lack of federal help in enforcing the laws. US Marshals have assisted in provided security at justice's homes.

Youngkin's spokesperson Christian Martinez said in a statement the governor agrees with the need to enforce anti-picketing laws in front of the home's of Supreme Court justices but pinned the lack of enforcement on local officials.

Youngkin "welcomes the Marshal of the Supreme Court's request for Fairfax County to enforce state law as they are the primary enforcement authority for the state statute," Martinez said.

Martinez added Youngkin is calling on Attorney General Merrick Garland to enforce any federal laws on the matter. CNN is reaching out to the US Department of Justice for comment on that.

Following the leak of the draft opinion in May, the Department of Homeland Security issued a memo warning law enforcement there are potential threats to Supreme Court members and the court's police have noticed a major uptick in social media threats of violence, with some prompting investigation.

Garland said at the time he met with the marshal of the Supreme Court, the FBI and others "to be sure that we were assessing all possible threats and providing all resources available."

Following the arrest near Kavanaugh's house, Hogan said in a statement there had been "heightened security" at the homes of justices since May.

"It is vital to our constitutional system that the justices be able to carry out their duties without fear of violence against them and their families," Hogan said. "We will continue to partner with both federal and local law enforcement officials to help ensure these residential areas are secure."

Maryland law prohibits a person from "intentionally assembl(ing) with another in a manner that disrupts a person's right to tranquility in the person's home."

Under a Montgomery County ordinance, an individual or group "must not picket in front of or adjacent to any private residence" but a group can be allowed to march in a residential area "without stopping at any particular private residence." Picketing is defined as "to post a person or persons at a particular place to convey a message."

In an interview last month, Marcus Jones, the chief of police in Montgomery County, told CNN there are "state and local laws that pertain to protests."

"They are allowed to be in the neighborhoods, but they must continuously walk, they cannot stand specifically in front of a neighborhood with signs and bullhorns and yelling at the residents," Jones said about the rules for protesters. "They must not block sidewalks, and they must not block the streets."

"If they violate any of those ... particular regulations, then we will arrest them," he added.
