Let (T_n) in L(E,F), where
E is the sequence Banach space l_infinity, and
F is the sequence Banach space l_1,
s.t. ||T_n|| <= 1 for all n.

Is it true that (T_n) has a pointwisely convergent subsequence (T_n_k), i.e. there is some T in L(E,F) s.t.
T_n_k(x) -> Tx for all x in E ? If so, why ?

TIA

I mean T_n_k(x) -> Tx in the weak-star topology of l_1.
