DENVER — The back-and-forth continues between constituents of embattled Senate President John Morse over which side’s tactics in an ongoing recall fight are more deplorable.

On Monday, the group leading the charge to recall Morse, D-Colorado Springs, for his support of gun control legislation, held a press conference and accused Morse’s team of harassing and intimidating those who signed recall petitions over the past several months.

“We have a constituent who was called and threatened that he might be audited,” said Jennifer Kerns, a spokeswoman for the group Basic Freedoms Defense Fund. “We have a senior citizen who was contacted and, in her words, she was ‘startled’, because when she asked who they were, they wouldn’t tell her.”

It’s a response to Friday’s press conference by Morse’s team, which announced that at least 50 people who allegedly signed petitions in fact did not, calling into question whether more recall petitions were forgeries.

The group “A Whole Lot of People for John Morse” has been trying to verify signatures for a few weeks, ever since Secretary of State Scott Gessler announced that more than enough signatures had been validated and that a recall election should be set.

Meanwhile, Morse has protested Gessler’s ruling and his lawyers argued last week that all the petitions should be thrown out because they didn’t include any language informing signers that they’d have to pick a replacement for Morse should he be recalled.

Deputy Secretary of State Suzanne Staiert is expected to rule on the protest by Wednesday.
