Let $A$ be a real symmetric matrix of order $n$ and $B=\begin{bmatrix}v &v &v &v\end{bmatrix}$ where $v$ is a non zero real column vector of dimension $n$. Consider $$C=\begin{bmatrix}A &B\\B^T &0\end{bmatrix}$$
and $$D=\begin{bmatrix}A &v\\v^T &0\end{bmatrix}$$ Let $P$ be any $n$ order principal submatrix of $D$. Suppose $\lambda_1\ge\lambda_2\ge\ldots\ge\lambda_{d}$ be first non zero eigenvalues of $C$  and $\mu_1\ge \mu_2 \ge \ldots \ge \mu_n$ be eigenvalues of $P$. 

Is it true that $\lambda_i\ge\mu_i\ge\lambda_{i+1}$ for $i=1,2,\ldots,d$?  (By interlacing property first inequality is obvious.)
