Senate Intelligence Committee member Sen. Dan Coats of Indiana told ABC's "This Week" that there are questions over whether Dzhokhar Tsarnaev (joh-KHAR' tsahr-NEYE'-ehv) will be able to talk again.
Coats said that doesn't mean the 19-year-old can't communicate, but he's "in a condition where we can't get any information from him at all."
Tsarnaev was captured from a tarp-covered boat in a suburban Boston yard Friday night and remained hospitalized in serious condition Sunday.
Tsarnaev and his 26-year-old brother, Tamerlan, were in a shootout with police early Friday. Tamerlan was killed and Dzhokhar fled the scene bleeding.
