His campaign released photos of Trone at what it described as meet-and-greets last week in Montgomery and Frederick counties, both of which are within the 6th Congressional District, which stretches to Western Maryland.
Trone, the co-founder of Total Wine & More, is facing Republican Amie Hoeber in the Nov. 6 general election. Delaney is vacating the seat to run for president.
Trone announced that he had cancer in late August, two months after learning that he had a tumor in his urinary tract. By the time of his announcement, he had undergone chemotherapy, which caused him to lose his hair and at least 15 pounds.
Surgeons removed one of his kidneys on Sept. 11, after which, as expected, he remained out of public view until late last week.
Along with Trone’s announcement, the campaign released a statement from the businessman’s doctor, who said that no radiation or additional chemotherapy is necessary “at this time.”
“David’s underlying health is strong,” said Phillip Pierorazio of the Brady Urological Institute and Department of Urology at Johns Hopkins University’s School of Medicine. “All of us believe he will continue a full range of physical activities and, if elected, will be able to carry out all the duties of a member of the House of Representatives.”
Trone spent more than $10 million of his fortune on his way to winning the Democratic primary in June. He is scheduled to appear at candidate forums on Oct. 23 and Oct. 24.
