The Boston Globe is reporting that Sen. Ted Kennedy is expected to attend the Democratic National Convention and deliver a speech on Tuesday night. His entire family is said to be gathering in Denver and will hear Kennedy's speech from a special section reserved for them:

In a development that is sure to bring the house down, US Senator Edward M. Kennedy is expected to attend the Democratic National Convention, most likely to deliver a speech tomorrow night.

Kennedy is battling brain cancer, and his doctors are said to be worried that his treatment has compromised his immune system and that attending the convention could put him at further risk. Still, the senator has recently told people that he has a speech written for the convention and that he badly wants to come, pending a final medical consultation.

Buzz has built among Massachusetts politicos that Kennedy would come, and today a source close to the family confirmed that he had made a decision to come.

``He is definitely planning to be here,'' said the Kennedy family confidant. ``The whole Kennedy family will be in a special section. It should be quite moment.''

Kennedy's family is also convening in Denver, including sister Jean Kennedy Smith, sister-in-law Ethel, nephews Joe and Stephen Smith, and nieces Kathleen Kennedy and Caroline Kennedy, who will also address the convention.

A Kennedy speech is usually a convention highlight, and Kennedy revels in an address that elicits a regular response from the crowd.

Given Kennedy's illness, this year's speech should be especially poignant.

The senator was very active in the primary campaign, endorsing Barack Obama and hitting the campaign trail for him.
